1) To prepare a hotter and more saturated Copper(II) Sulphate Solution
- Put a LOT of raw Copper(II) Sulphate crystal into a beaker and pour HOT boiling water onto them. Remember don't pour too much water into it - The water must NOT dissolve all the crystal (The trick is: more raw crystal less hot water!)
- Stir the mixture gently for 5 minutes
- While the mixture is still very hot, filter out the blue solution (the Filtrate) using funnel and filter paper
2) Now, quickly hang your Copper(II) Sulphate "seed" in the middle of the filtrate (saturated Copper(II) Sulphate Solution)
3) Next, wait until the solution cool down to room temperature. By that time, the crystal seed should grow much better! Placing the beaker in a windy place also helps faster crystallization
4) If you want to grow the crystal seed bigger, take it out, heat up the remaining filtrate, and use this heated filtrate as "hot water" and repeat steps (1-3)!
