What will happen if you keep copper sulphate crystals in water?

Question

Answer

If copper sulphate crystals are added to water then, the particles of copper sulphate crystals loses attraction between them and starts moving continuously and gets mixed up with water. It is called 'hydrated copper sulphate solution which is having a blue colour.

Answer

They will get mixed in the water completely and gives the water a blue colour.

Answer

Effect of keeping copper sulphate crystals in water

1. Dissolution of copper sulphate crystals:
When copper sulphate crystals are kept in water, they start to dissolve in the water. The water molecules surround the copper and sulphate ions present in the crystal lattice, breaking them apart and forming a solution of copper sulphate.

2. Formation of a blue colored solution:
As the copper sulphate crystals dissolve in water, they impart a blue color to the solution. This is due to the presence of copper ions in the solution, which have a blue color in aqueous form.

3. Increase in concentration of copper ions:
The concentration of copper ions in the solution increases as more copper sulphate crystals dissolve in water. This higher concentration of copper ions makes the solution more saturated with copper sulphate.

4. Equilibrium between dissolved and undissolved copper sulphate:
As more copper sulphate crystals dissolve in water, there reaches a point where the rate of dissolution is equal to the rate of re-crystallization. This establishes an equilibrium between dissolved and undissolved copper sulphate in the solution.

5. Saturation of the solution:
Eventually, the solution becomes saturated with copper sulphate, meaning it cannot dissolve any more of the crystals. At this point, any additional copper sulphate crystals added to the solution will not dissolve and will settle at the bottom of the container.
In conclusion, keeping copper sulphate crystals in water results in the formation of a blue colored solution due to the dissolution of the crystals. The concentration of copper ions increases in the solution until it reaches saturation, after which no more crystals can dissolve.
