Zinc sulphate crystals making process:

• Use a beaker, to place 100ml of sulphuric acid into it and slowly add  zinc powder while stirring till the time no more fizz occurs or some zinc powder remains unreacted.
• Use the filter paper to separate the undissolved / unreacted metal and split the filtrate into two.
• Heat one portion of the filtrate to dryness and heat the other portion until its volume reduces to half. Use a filter paper to cover the solution and leave it for a day or two.
• Zinc sulphate crystals are produced.
