NEET Chemistry Redox Reactions Questions Solved


One gm. of a metal carbonate gave 0.56 gm. of its oxide on heating. The equivalent mass of the metal is

(1) 40

(2) 30

(3) 20

(4) 10

(3) Mass of metal carbonateMass of metal oxide  =  + Eq. mass of CO32+ Eq. mass of O22 or 1.00.56=E+30E+8

or (E+8)  ×1.0=(E+30)(0.56) (Where E is the equivalent mass of the metal)

E = 20
