Question
1 g of the carbonate of a metal was dissolved in 25 mL of 1N-HCl. The resulting liquid required 5 mL of 1N-NaOH for naturalization. The Equivalent wt of the metal carbonate is
Options
A.50
B.30
C.20
D.None
Solution
Total HCl ⇒ 25 × 1 = 25 m Eq
Excess HCl ⇒ 5 × 1 = 5 m Eq
HCl used ⇒ 25 - 5 = 20 m Eq
∴ m Eq = of HCl = m Eq of carbonate
Eq = 
of carbonate = 1/E
∴ E =
= 50
Excess HCl ⇒ 5 × 1 = 5 m Eq
