What is the pH of the resulting solution when equal volumes of 0.1 M NaOH and 0.01 M HCl are mixed?NEET 2015 (Phase 2)

Options:

Answer:

Solution:

$N_{1} V_{1} - N_{2} V_{2} = N . V .$

$0.1 \times 1 - 0.01 \times 1 = N \times 2$

$[O H^{-}] = N_{net} = \frac{0.09}{2} = 0.045 N$

$p O H = - l o g (0.045) = 1.35$

$∴ p H = 14 - p O H = 14 - 1.35 = 12.65$
