2 What is the correct sequence of steps for the preparation of a pure sample of copper(II) sulfate
Lina20 [59]

Answer:

The correct answer is - B. dissolving → evaporation filtration → crystallisation

Explanation:

The method of the preparation of a pure sample of copper(II) sulfate from dilute sulfuric acid and copper II oxide is given as follows:

step 1. Adding dilute sulfuric acid into a beaker. Using bunsen burner heat the beaker.

step 2. Adding the copper (II) oxide into the beaker and give it a little time at a time to the warm dilute sulfuric acid and stir

step 3. Filtering the mixture into an evaporating vessel to remove the excess copper (II) oxide and water from the filtrate.

Step 4. leave the rest filtrate to crystallize.

Copper (II) Oxide  {CuO (s)}  +  Dilute Sulfuric Acid {H2SO4 (aq)}   →  Copper (II) Sulphate {CuSO4 (s)}   +  Water {H2O}
