Can anyone provide some information on crystalization of copper sulphate?
Copper carbonate powder is added to sulphuric acid until the copper carbonate stops reacting with the acid (the fizzing stops) and you are left with a azure blue liquid, called copper sulphate. The fizzing stopped because the copper carbonate has reacted with all of the sulphuric acid available and hence, there is now copper carbonate in excess. The copper sulphate solution must now be filtered to remove excess copper carbonate. Next, the solution must be reduced (by roughly half or more) by heating the solution (usually over a bunsen burner). The now reduced solution is transferred to an evaporating dish or china dish and left over the course of a few days (at most) to naturally evaporate leaving behind blue crystals.
