Calculate the pH value of the followings :
0.001 M HCl

Text Solution

Verified by Experts

Since of HCl is a strong acid, it ionises completely.
`therefore [H_(3)O^(+)] = [HCl] = 0.001 M = 1 xx 10^(-3)M`
We know that , `pH = -log[H_(3)O^(+)] = -log [1 xx 10^(-3)] = -log 1 + 3 log 10 = 3 [because log 1 = 0, log 10 = 1]`
