What is The number of gram equivalents in 1 litre of a solution is known as: and explain in detail?
Electrical equivalence is not necessarily the same as chemical equivalence. A gram equivalent is the weight of a substance that is chemically equivalent to 8.000 g of oxygen. The normality (N) of a solution is the number of gram equivalents in 1 liter. A 1 N solution of hydrochloric acid contains both H+ (1 g) and Cl- (35.5 g) equivalents, = (1 g + 35.5 g)/L = 36.5 g/L.
