Question

Is Copper sulphate a mixture or a compound? Why?

Answer 1

Answer:

Mixture:

• When two or more substances are mixed without having any chemical change, then the final substance is known as a mixture.
• Its components can be separated easily by physical means.
• For example, a mixture of salt in Water$\left({\mathrm{H}}_2\mathrm{O}\right)$.

Compound:

• A pure substance constituted of two or more elements combined chemically in a fixed ratio is called a compound.
• It can be split into these simpler and different substances by chemical means.
• For example, Copper sulphate$\left({\mathrm{CuSO}}_4\right)$.

Copper sulphate$\left({\mathrm{CuSO}}_4\right)$ as a compound:

• Copper sulphate is the compound of Copper$\left(Cu\right)$, Sulphur$\left(S\right)$, and Oxygen$\left(\mathrm{O}\right)$.
• These elements are combined chemically in a fixed ratio to form Copper sulphate.
• We can not separate these components easily by physical means.
• So, Copper sulphate is a compound, not a mixture

Conclusion:

Therefore, Copper sulphate$\left({\mathrm{CuSO}}_4\right)$ is a compound, not a mixture.
