Question

Following five solutions of $KOH$ were prepared as: first, 0.1 mole in 1 L; second, 0.2 mole in 2 L; third, 0.3 mole in 3 L; fourth, 0.4 mole in 4 L; fifth, 0.5 mole in 5 L. The pH of resultant solution, when all these solutions are mixed, is

Prashant Kotian · Accepted Answer

Correct answer: C. Each solution has the same concentration: 0.1 M . Mixing identical concentrations gives the same concentration: [OH-] = 0.1 M. pOH = 1. pH = 13.
