M.eq. of 0.2M H2SO4=(2 × 0.2 M/1000)× 100=0.04 M.eq.of.2MNaOH =(0.2/1000)× 100=0.02 left [.H+].=0.04-0.02=0.02 . Total volume =200=(. 02/200)=.0001=10- 4M pH=4 .

Q. What is the nature of the resulting solution prepared from $100 m l$ of $0.2 M H_{2} S O_{4}$ added to $100 m l$ of $0.2 MN a O H .$

Neutral

Acidic

Basic

Slightly basic

M.eq. of 0.2M $H_{2} S O_{4} = \frac{2 \times 0.2 M}{1000} \times 100 = 0.04$
$M . e q . o f .2 MN a O H$ $= \frac{0.2}{1000} \times 100 = 0.02$
left $[H^{+}] = 0.04 - 0.02 = 0.02$ .
Total volume $= 200 = \frac{.02}{200} = .0001 = 1 0^{- 4} M$
$p H = 4$ .
