Question

describe how crystal of copper sulphate are produced​

Answer 1

Answer:

From an impure sample of copper sulphate crystals of copper sulphate are produced by the process of crystallization through the following steps:

1. Some impure sample of copper sulphate is taken in a china dish.
2. It is dissolved in minimum amount of boiling water.
3. The impurities and undissolved copper sulphate are separated by filtration. Thus a hot saturated solution of copper sulphate is produced.
4. The solution is covered with a filter paper and left undisturbed at room temperature to cool slowly.
5. After sometime the crystals of copper sulphate are produced on the china dish.

Answer 2

Hydrogen is made, as well as copper sulfate solution. It can also be made by reacting copper(II) oxide or copper(II) hydroxide or copper(II) carbonate with sulfuric acid or by adding copper to heated concentrated sulphuric acid: ... It can also be made by reacting copper with a mixture of nitric acid and sulfuric acid.
