take a base (e.g. powdered copper oxide) and mix with a heated acid (e.g. concentrated sulphuric acid) to cause a neutralisation reaction that produces a salt solution (copper sulphate solution in this case)
step 2:
add excesscopper oxide indicated by unreacted powder at the bottom of the beaker
step 3:
using a filter funnel and filter paper, filter the solution into a conical flask
step 4 :
pour filtrate into an evapourating basin on a beaker of water over a tripod, gauze and bunsen burner and heat gently
once crystals have started to form pour remaining solution into a crystalising dish and leave for at least 24 hours
remove crystals with a spatula and pat dry between 2 peices of filter paper to remove any remaining solution
