The pH of a 0.1 M solution of

\mathrm{N}{\mathrm{H}_4}\mathrm{OH}

(having

{K_b} = 1.0 \times {10^{ - 5}})

is equal to

View answer and explanation

Correct option: C

Option C (11) is correct because NH4OH is a weak base, and the pH can be calculated using the Kb value and the concentration of the base.
