2 grams of a metal hydroxide, on ignition, gave 1.51 grams of oxide. Equivalent weight of metal is (A) 40 g (B) 20 g (C) 23 g (D) 46 g

Tardigrade Admin · Accepted Answer

(w1/w2) = (E1/E2) (2/1.51) = (Eq wt. of metal + Eq. wt. of hydroxideion/Eq. wt. of metal + Eq. wt. of oxygen) E = 20 (2/1.15) = (E + 17/E + 8)
