A quantity of 4 g of impure limestone was treated with 250 ml of dil. . After completion of the reaction a small quantity of residue was left and 1120 ml of a gas was evolved at 0°C and 1 atm. The normality of the acid solution is
Options:
Answer:
C
Solution:
= 1120/22400 = 0.05 mol. + 2HCl , so = 2 0.05 = 0.1 mol, fully consumed since residue (excess carbonate) remains. Normality = 0.1/0.25 = 0.4 N, option (c).
