Question

Assertion:On dilution of a strong acid or a weak acid,the number of H+ ions per unit volume in the solution decreases. Reason:Dissociation of strong acid does not increase with dilution whereas that of weak acid increases with dilution.​

Answer 1

The assertion is true, but the reason is false.

Explanation:

• When acid is diluted with water its concentration decreases due to a decrease in the number of hydronium ions.
• Dilution means to add more water to make the acid less concentrated.
• The number of hydronium ion decreases because only water is added and the overall volume of the solution increases.
• An increase in volume means a drop in the number of ions  

Answer 2

Answer:

THE ASSERTION IS TRUE BUT THE REASON IS FALSE
