What is the pH of the resulting solution when equal volumes of 0.1 m NaOH and 0.01 M HCl are mixed?

(1) 7.0

(2) 1.04

(3) 12.65

(4) 2.0

 

Correct Answer: (3) 12.65

Explanation:

With the formula, N1V1 – N2V2 = N x V

The pH of the resulting solution when equal volumes of 0.1 m NaOH and 0.01 M HCl are mixed is 12.65
