Question

Q.15 Reason: The strength of acids and bases depends on the number of Hand OH-ions produced.
Assertion : The process of dissolving an acid or base in water is highly endothermic.​

Answer 1

Answer:

A salt of strong acid with a  strong base does not undergo hydrolysis. In this case, neither the cations nor the anions undergoes hydrolysis. Therefor the solution remains neutral. For example: in the aqueous solution of NaCl, its ions Na+ and Cl− ions have no tendency to react with H+ or OH− ions of water. This is because the possible products of such reaction are NaOH and HCl, which are they completely dissociated. As a result, there is no change in the concentration of H+ and OH− ions and hence the solution continues to remain neutral.
