Answers
Answer:
A salt is a compound formed from an acid by the replacement of the hydrogen in the acid by a metal. Therefore, it is formed when acids react with bases. Generally, we represent salt as Sodium Chloride but it is not like that. In fact, Sodium Chloride is just one member of a huge family of compounds called salts.
1. The acidic nature and basic nature of some salt solutions can be explained on the basis of:
A. Splitting of a salt compound
B. Hydrolysis of salts
C. Both A and B
D. Only B
Ans. C
Explanation: The acidic nature and basic nature of some salt solutions can be explained on the basis of hydrolysis of salts. Here, hydrolysis means splitting up of a compound by the action of water.
2. Which salt is used as a raw material for making a large number of useful chemicals in industry?
A. Sodium Chloride
B. Ammonium Hydroxide
C. Ammonium Chloride
D. Sodium Nitrate
Ans. A
Explanation: Common Salt that is Sodium Chloride is used as a raw material for making a large number of useful chemicals in industry.
3. Which of the following salts will give an aqueous solution having pH of almost 7?
A. Sodium Carbonate
B. Ammonium Nitrate
C. Potassium Chloride
D. Calcium Chloride
Ans. C
Explanation: Potassium Chloride salt will give an aqueous solution having pH of almost 7.
4. Name the salt whose aqueous solution will have no effect on either red litmus or blue litmus?
A. Potassium Sulphate
B. Sodium Chloride
C. Sodium Carbonate
D. Ammonium Sulphate
Ans. A
Explanation: Aqueous solution of potassium sulphate salt will have no effect on either red litmus or blue litmus.
5. Name the salt when on dissolving in water give an acidic solution?
A. Potassium Chloride
B. Ammonium Chloride
C. Sodium Carbonate
D. Sodium Acetate
Ans. B
Explanation: Ammonium Chloride salt on dissolving in water gives an acidic solution.
