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


(iii) Lower the pH, stronger the base


(iv) Lower the pH, weaker the base

The value of pH is inversely related with the concentration of hydrogen ions. Hence, Higher the pH, weaker the acid and Lower the pH, weaker the base.
