100  mL  of  mixture  of  NaOH  and  Na₂SO₄  is neutralised  by  10  mL  of  0.5  M  H₂SO₄.  Hence, NaOH in 100 mL solution is

A.0.2 g
B.0.4 g✓ Correct
C.0.6 g
D.None
Explanation

Sodium  sulphate  is  neutral,  therefore,  NaOH  is neutralized by sulphuric acid only. Equivalents of NaOH= Equivalents of Sulphuric acid 3 2 1000 100 1 10 10 0.5 2 40 100 1000 40 10 0.4 w W g x xx x x x x x
