Text solutionVerified

pH = 1; H^{+} = 1 0^{- 1} = 0.1 M

pH = 2; H^{+} = 1 0^{- 2} = 0.01 M ∴ M_{1} = 0.1 V_{1} = 1

From

pH = M_{2} = 2; H^{+} = 1 0^{- 2} = 0. ∴ M_{1} = 0.1 V 0.01, V_{2} = ?

From

M_{1} V_{1} = M_{2} V_{2} 0.1 \times 1 = 0.01 \times V_{2} V_{2} = 10 L

∴

Volume of water added

= 10 - 1 = 9 L
