Question

Which of the following statements is correct about an aqueous solution of an acid and of a base?
(i) Higher the pH, stronger the acid
(ii) Higher the pH, weaker the acid
(in) Lower the pH, stronger the base
(iv) Lower the pH, weaker the base
(a) (i) and (iii)​

Answer 1

Answer:

- When the pH of an aqueous solution is higher, acidic properties are weak. Thus it is a base. When the pH an aqueous solution is lower, basic properties are weak...

Explanation:

ii and iv are correct

I hope it will help you

Answer 2

Answer:

The pH scale starts from 0 and ends at 14, 0 indicating most acidic and 14 indicating most basic. The pH value of 7 indicates neutrality. Hence lower the pH, weaker the base and higher the pH, weaker the acid. Therefore, the correct statements are (ii) and (iv)
