FAQs on Acids and Bases - Chemistry, General Science, Exam Preparation Video Lecture - General Awareness & Knowledge - Bank Exams

1. What is an acid?
An acid is a chemical substance that donates protons (H+) or accepts electrons during a chemical reaction. Acids typically have a sour taste, can corrode metals, and turn blue litmus paper red.
2. What is a base?
A base is a chemical substance that accepts protons (H+) or donates electrons during a chemical reaction. Bases usually have a bitter taste, feel slippery, and turn red litmus paper blue.
3. How do acids and bases react with each other?
When an acid reacts with a base, they undergo a neutralization reaction, resulting in the formation of water and a salt. The acid donates its proton to the base, forming water, while the anion from the acid combines with the cation from the base to form the salt.
4. What are some common examples of acids and bases?
Some common examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH). Common examples of bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2).
5. How are acids and bases measured?
The acidity or basicity of a substance is measured using the pH scale. The pH scale ranges from 0 to 14, where 0 represents a strong acid, 7 is neutral, and 14 represents a strong base. pH values below 7 indicate acidity, while values above 7 indicate alkalinity or basicity.
