1. Why do you need to crystallize Copper Sulphate ?
2. Through an activity show the process of crystallization with the relevant diagram.
3. What is the molar mass of anhydrous copper sulphate ?
4. in copper sulphate what is the valency of copper?
Answers
1. you seen crystals of salts crystals aremade through a process ofcrystallization. let us try to make salt crystals from a solution of salt for thiswe need thread a saturated. solution ofcopper sulfate and copper sulfate. firstwe will make a supersaturated solution of copper sulphate light.
2. First of all, take some water in a beaker. Add a few drops of dilute Sulphuric Acid(H2SO4).
Heat the mixture on a burner. Add Copper Sulphate Powder when it starts boiling.
Keep stirring the solution. Keep adding Copper Sulphate Powder to the solution until it is soluble.
Now filter the solution and allow it to cool down.
You will see crystals of copper sulphate suspended in the solution
3. 159.609 g/mol(anhydrous) 249.685 g/mol (pentahydrate)
4. As transition metal it possesses a property which is that it has variablevalency. This means that the metal can have different valencies in different scenarios. So in copper sulphate or CuSO4, the valency of copper is +2 where as in Cu2O or copper oxide its valency is +1.
