FAQs on Video: PH of Salts(Easy Explanation) Video Lecture - Class 10

1. What is the pH of a salt?
Ans. The pH of a salt depends on the nature of the salt. Some salts are acidic in nature and have a pH below 7, while others are basic and have a pH above 7. Neutral salts have a pH of 7.
2. How is the pH of a salt determined?
Ans. The pH of a salt can be determined by analyzing the ions it contains. If the salt contains a cation that is highly acidic or a strong acid anion, it will have an acidic pH. On the other hand, if the salt contains a cation that is highly basic or a strong base anion, it will have a basic pH.
3. Can salts affect the pH of a solution?
Ans. Yes, salts can affect the pH of a solution. When a salt dissolves in water, it dissociates into its constituent ions. These ions can either be acidic or basic, depending on their nature. The presence of these ions can alter the pH of the solution.
4. Give an example of an acidic salt.
Ans. An example of an acidic salt is ammonium chloride (NH4Cl). When it dissolves in water, it forms ammonium ions (NH4+) and chloride ions (Cl-). The ammonium ion is acidic in nature, leading to an acidic pH.
5. Provide an example of a basic salt.
Ans. An example of a basic salt is sodium bicarbonate (NaHCO3). When it dissolves in water, it forms sodium ions (Na+) and bicarbonate ions (HCO3-). The bicarbonate ion acts as a weak base, resulting in a basic pH.
