A metal M forms the sulphate `M_(2)(SO_(4))_(3)`. A 0.596 gram sample of the sulphate reacts with excess `BaCl_(2)` to give 1.220 g `BaSO_(4)`. What is the atomic mass of M ?

What is the normality of sulphate ions in 1M Al_(2)(SO_(4))_(3) solution?

In a double sulphate salt K_(2)SO_(4)Al_(2)(SO_(4))_(3)4xx xH_(2)O . The value of x is

100 gms of 118% oleum reacted with excess water. How much H_(2)SO_(4) is formed?

Calculate the molecular weight of alumunum sulphate Al_(2)(SO_(4))_(3)

Density of potassium is 2.64 xx 10^(6) g m^(-3) . What is the radius of metal atom?

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. When BaCl_(2) solution is added in aq. Solution of NaHSO_(4) a white ppt. is obtained which is of:

0.12g of organic compound containing sulphur on treatment with Conc. HNO_(3) in a carius tube and then with excess of BaCl_(2) produced 0.233g of BaSO_(4) . % of 'S' in compound ...........

A metal M readily forms its sulphate MSO_(4) which is water soluble. It forms oxide Mo which becomes inert on heating. It forms insouble hydroxide which is soluble NaOH. The metal is
