Question

Identify the type of reaction given below.
Copper (II) oxide, a black solid, and colourless dilute sulphuric acid react to produce copper
(II) sulphate, giving a characteristic blue colour to the solution. Blue copper (II) sulphate
pentahydrate crystals are obtained from this solution.

Answer 1

Answer:

Copper(II) oxide, a black solid and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution.

Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate,giving a characteristic blue colour to the solution.

Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate and on heating copper sulfate pentahydrate turns white due to loss of water from blue copper sulfate.It has water of hydration  which forms water vapour on heating, leaving white anhydrous copper sulphate.
