NCERT Class 10 Science Activity 2.14 Explanation

 

 

Activity- Collect the following salt samples – sodium chloride, potassium nitrate, aluminium chloride, zinc suplhate, copper sulphate, sodium acetate, sodium carbonate and sodium hydrogen carbonate (some other salts available can also be taken).

·      Check their solubility in water (use distilled water only).

·      Check the action of these solutions on litmus paper and find the pH using a pH paper.

·      Which of the salts are acidic, basic or neutral?

·      Identify the acid or base used to form the salt.

·      Report your observations in the table given below

 

S. No.	Salt	Formula	Solubility in water	Action on litmus	pH	Acid used	Base used
