What is the pH of the acid which is used in the formation of common salt?
(A) Between 1 to 3
(B) Between 6 to 8
(C) Between 8 to 10
(D) Between 11 to 13
To make salt neutral, we need strong acid and strong base to make salt.
So, for the formation of common salt the pH of the acid is between 1 to 3,
Hence, the correct answer is (a)
