Chemistry
(a) If you are given some copper sulphate crystals, how would you proceed to prepare its saturated solution at room temperature?
(b) How can you show that your solution is really saturated?
Answer
(a) Preparation of saturated solution of copper sulphate crystals:
Take 100 g of distilled water in a beaker. Add one gram of copper sulphate crystals and stir with a glass rod till the crystals dissolve. Add one more gram of copper sulphate crystals and stir it. It too will dissolve. Continue adding a gram of copper sulphate crystals and stir vigorously after each addition.
A stage is reached when no more copper sulphate dissolves. At this stage, we have a saturated solution of copper sulphate at room temperature.
(b) Add some more copper sulphate crystals to the saturated solution. The crystals do not dissolve no matter how long it is left there or how vigorously it is stirred.
