The sulphate of a metal `M` contains `9.87%` of `M`, This sulphate is isomorphous with `ZnSO_(4).7H_(2)O`. The atomic weight of `M` is

The sulphate of an element contains 42.2% element. The equivalent mass would be

The oxide of a metal contains 40% of oxygen. The valency of metal is 2. What is the atomic weight of metal?

Li_(2)SO_(4) is not isomorphous with sodium sulphate

The formula of a metal chloride is MCl_3 and it contains 20% of the metal.The atomic weight of the metal is approxiamately

CuSO_(4). 5H_(2)O has pale blue colour while ZnSO_(4), 7h_(2)O is white. Discuss.

Passage-I : Metallic sulphates can be obtained by reacting the metals (above hydrogen in ECS), or its oxide, hydroxide or carbonate with dil. H_(2)SO_(4) . Group IA metals also form hydrogen sulphates which can be isolated in solid. In general metal sulphates are soluble in water and crystallize with water of crystallization. Sulphates are thermally more stable than nitrates. Which metal sulphate will decompose into SO_(3) and metal oxide when heated:

0.72 gm of an oxide of a metal M on reduction with H_(2) gave 0.64 g of the metal . The atomic weight of the metal is 64 . The empirical formula of the compound is
