Answer:
Step-by-step explanation:
To obtain pure crystals of iron sulfate from a mixture of copper carbonate and iron sulfate, you can use the process of filtration and crystallization. Here are the steps to follow:
Dissolve the mixture of copper carbonate and iron sulfate in water to form a solution.
Add dilute sulfuric acid to the solution, which will react with copper carbonate to form copper sulfate, carbon dioxide, and water. The iron sulfate will remain in the solution.
CuCO3 + H2SO4 -> CuSO4 + CO2 + H2O
Filter the solution to separate the solid copper sulfate from the iron sulfate solution.
Heat the iron sulfate solution to evaporate the water, leaving behind a concentrated solution of iron sulfate.
Allow the concentrated solution to cool slowly to room temperature to allow crystals of pure iron sulfate to form.
Filter the crystalized iron sulfate to separate it from any remaining solution.
Wash the crystals with distilled water to remove any impurities and allow them to dry.
By following these steps, you can obtain pure crystals of iron sulfate from a mixture of copper carbonate and iron sulfate.
