Q. If x g of a metal forms y g of metal chloride, equivalent weight of metal is

Redox Reactions

Solution:

Wt of the metal = x g
Wt. of metal chloride = y g
Wt. of chloride = (y - x) g
(y - x) g of chloride combines with x g of metal.
35.5 g of chloride combines with $\frac{x}{(y -x)} \times 35.5$ g of metal.
Hence, equivalent mass of metal = $\frac{35.5 x}{y - x}$
