Important Questions on Acids, Bases and Salts for Class 10
Important questions on acids, bases and salts cover all difficulty levels, from very short answers worth 1-2 marks to long answers worth 5 marks. Examiners typically ask about definitions of acids and bases, properties of acids and bases, the pH scale and indicators, types of salt formation, and practical applications like the importance of pH in everyday life. Students who practice these question types perform significantly better on board papers.
Most board papers include questions asking students to distinguish between strong and weak acids, identify bases using indicators, or explain acid-base reactions. Case-based questions are increasingly common, requiring students to apply chemistry concepts to real-world scenarios like soil pH or industrial processes.

Master acids, bases and salts by practicing questions ranging from one-mark definitions to five-mark explanations, ensuring comprehensive preparation for your board examination.
Properties of Acids and Bases: Key Concepts for Class 10
The properties of acids and properties of bases form the foundation for understanding acid-base chemistry. Common properties of acids include sour taste, turning blue litmus red, and reacting with metals and bases. Properties of bases include bitter taste, slippery feel, and turning red litmus blue. Students frequently confuse universal indicator results or misidentify whether a substance is an acid or base by pH value alone.
Understanding these properties goes beyond memorization-you must apply them to identify unknown substances and predict reaction outcomes. For instance, when an acid reacts with a base, the characteristic properties of both are neutralized, forming salt and water. This neutralization concept appears in multiple question types, from short answers to diagram-based questions requiring you to label the acid, base, salt, and water produced.

pH Scale and Indicators: Complete Guide for Class 10 Students
The pH scale and indicators are critical topics that test both theoretical understanding and practical application skills. The pH scale ranges from 0-14, where 7 is neutral, values below 7 indicate acids, and values above 7 indicate bases. Students often struggle to remember that lower pH means more acidic, not less acidic. Indicators like litmus paper, methyl orange, and phenolphthalein change color at specific pH ranges, making them essential tools for identifying acids and bases.
Types of indicators include natural indicators (like turmeric and red cabbage), synthetic indicators (like methyl orange), and universal indicator papers that show pH values by color matching. Board exams frequently ask students to select appropriate indicators for specific applications or explain why certain indicators work better for strong versus weak acids. The importance of pH in everyday life includes soil pH for agriculture, body pH for human health, and industrial applications requiring specific pH levels.

Case Based Questions and Assertion-Reason Questions on Acids, Bases and Salts
Case-based questions present real-world scenarios requiring you to apply acids, bases and salts concepts to solve problems. These questions test deeper understanding beyond rote memorization-for example, a case might describe a farmer with acidic soil needing to choose the right substance to neutralize it, requiring you to identify appropriate bases and explain the chemical reaction occurring.
Assertion-Reason questions test your ability to link concepts logically, presenting a statement and reason that you must evaluate for correctness. Many students answer these incorrectly by evaluating each part separately without checking if the reason actually explains the assertion. Practicing these question types improves your analytical skills and exam performance on higher-order thinking questions.

Frequently asked questions About Class 10 Examination
- What is the difference between acids and bases in simple terms?Ans. Acids are sour substances that release hydrogen ions in water, while bases are bitter substances that release hydroxide ions. Common acids include lemon juice and vinegar; common bases include baking soda and soap. The main difference lies in their chemical composition and how they react with indicators like litmus paper, which turns red for acids and blue for bases.
- How do you identify if a substance is acidic or basic using pH scale?Ans. The pH scale measures acidity or alkalinity on a 0-14 range. Substances with pH below 7 are acidic, those at pH 7 are neutral, and those above 7 are basic or alkaline. Students can use pH paper or digital pH meters to test unknown substances. Lower pH numbers indicate stronger acidity, while higher numbers indicate stronger basicity.
- What happens when you mix an acid and a base together?Ans. Mixing acids and bases causes a neutralisation reaction, producing salt and water as products. The acid's hydrogen ions combine with the base's hydroxide ions to form H₂O. This exothermic reaction releases heat energy. For example, hydrochloric acid reacting with sodium hydroxide produces sodium chloride salt and water, demonstrating how opposite substances cancel each other out.
- What are salts and how are they formed in chemistry?Ans. Salts are ionic compounds formed when an acid reacts completely with a base in neutralisation reactions. They consist of positive ions from the base and negative ions from the acid. Common examples include table salt (sodium chloride), Epsom salt, and calcium carbonate. Salts can be acidic, basic, or neutral depending on the acid-base pair that produced them.
- Why does litmus paper change colour with acids and bases?Ans. Litmus paper contains a natural pH indicator that responds to hydrogen and hydroxide ion concentrations. Red litmus turns blue in basic solutions due to increased hydroxide ions, while blue litmus turns red in acidic solutions with excess hydrogen ions. This colour change occurs because the dye's chemical structure alters at different pH levels, making litmus an effective and affordable testing tool for students.
- What are strong acids and weak acids with examples for Class 10?Ans. Strong acids completely ionise in water, releasing all hydrogen ions, including hydrochloric acid, nitric acid, and sulphuric acid. Weak acids partially ionise, retaining some molecular form, like acetic acid and carbonic acid. Strong acids conduct electricity better and react more vigorously than weak acids. Understanding this distinction helps predict reaction intensity and acid behaviour in chemical equations.
- How do you calculate the pH of an acid or base solution?Ans. pH is calculated using the formula: pH = -log[H⁺], where [H⁺] represents hydrogen ion concentration in moles per litre. For bases, pOH is calculated similarly, then converted using pH + pOH = 14. Students can also use pH charts or digital meters for practical measurements. This mathematical approach helps quantify acidity or alkalinity accurately without indicators.
- What are buffer solutions and why are they important?Ans. Buffer solutions resist pH changes when small amounts of acid or base are added, maintaining relatively stable acidity or alkalinity. They contain weak acids with their conjugate bases or weak bases with their conjugate acids. Buffers are vital in biological systems, industrial processes, and laboratory work. Blood maintains pH around 7.4 through buffering, demonstrating their critical role in living organisms and chemical applications.
- What is the difference between concentrated and dilute acids and bases?Ans. Concentrated acids and bases contain high solute amounts dissolved in small solvent volumes, making them highly corrosive and reactive. Dilute solutions contain less solute in larger solvent volumes, reducing reactivity and hazard. Concentration affects pH, conductivity, and reaction rates significantly. A dilute acid can still be very acidic if fully ionised, showing that concentration and strength represent different chemical properties requiring careful distinction.
- How do you write balanced chemical equations for acid-base neutralisation reactions?Ans. Balanced equations for neutralisation require equal atoms on both sides, following the format: Acid + Base → Salt + Water. Count hydrogen, oxygen, and other atoms carefully, adjusting coefficients until balanced. For example: HCl + NaOH → NaCl + H₂O. Students should practise identifying reactants, predicting products, and verifying balance using detailed notes and MCQ tests available on EduRev for structured learning.
