Give a test to distinguish dilute sulphuric acid from dilute HCl and dilute HNO_(3) .

Distinguish by dilute sulphuric acid: Copper and magnesium

Sulphuric acid is a dibasic acid in nature, hence it forms

Distinguish by dilute sulphuric acid. Sodium sulphite and sodium carbonate ?

Give reasons for the following Concentrated sulphuric acid is a weaker acid compared to dilute sulphuric acid.

When dilute sulphuric acid reacts with iron sulphide, the gas evolved is

Match (A) iron sulphide, (B) sodium thiosulphate, (C) calcium carbonate, (D) ammonium chloride, (E) concentrated sulphuric acid, (F) nitric acid, with its correct description given in (i) - (vi) below: (i) It forms colloidal sulphur when treated with dilute hydrochloric acid. (ii) When it is heated with an alkali a gas is formed which produces white fumes with HCI. (iii) It reacts with acids and a gas having smell like rotten eggs is liberated. (iv) It gives a brisk effervescence when treated with dilute sulphuric acid. (v) It gives ring test. (vi) It oxidises sulphur to sulphur dioxide.
