100 mL of mixture of NaOH and Na 2 SO 4 is neutralized by 10 mL of 0.5 M H 2 SO 4. Hence, NaOH in 100 mL solution is

Question

100 mL of mixture of NaOH and Na 2 SO 4 is neutralized by 10 mL of 0.5 M H 2 SO 4. Hence, NaOH in 100 mL solution is (A) 0.2 g (B) 0.4 g (C) 0.6 g (D) None

Tardigrade Admin · Accepted Answer

Na 2 SO 4 does not react N( NaOH )=0.1=4 g L -1 =0.4 g per 100 mL

Q. $100 m L$ of mixture of $N a O H$ and $N a_{2} S O_{4}$ is neutralized by $10 m L$ of $0.5 M H_{2} S O_{4}$ . Hence, $N a O H$ in $100 m L$ solution is

$0.2 g$

$0.4 g$

$0.6 g$

None

$N a_{2} S O_{4}$ does not react
$N (N a O H) = 0.1 = 4 g L^{- 1}$
$= 0.4 g$ per $100 m L$
