Question -

Which among the following has the highest normality?

Options:

A . 8 g of KOH per 100 ml of solution

B . 0.5 M sulphuric acid

C . 1 N phosphoric acid

D . 2 moles of NaOH per 1000 ml of solution

Answer: Option D
:
D

N = \frac{no.of equivalents}{Volume of solution(L)}

N of KOH =

\frac{[\frac{8}{56}]}{0.1} = 1.43 N

N of

H_{2} S O_{4}

= M

\times

n factor =

0.5 \times 2 = 1 N

equivalents of NaOH = moles

\times

n factor
=

2 \times 1 = 2

eq
N of NaOH =

\frac{2}{1} = 2
