Solution

The correct option is B $1$
Concentration of $H^{+}$ ions $= 0.1$ $m o l / L = 10^{- 1}$ $M$
$∴ p H = - log [H^{+}] = - log 10^{- 1} = 1$
$∴ p H = 1$

What is the pH of a solution that contains 0.1 mol/L of H3O+ ions?

The correct option is B 1Concentration of H+ ions =0.1 mol/L=10−1 M∴pH=−log[H+]=−log10−1=1∴pH=1
