A student wants to prepare crystals of zinc sulfate by reacting excess zinc carbonate with dilute sulfuric acid.
ZnCO₃(s) + H₂SO₄(aq) → ZnSO₄(aq) + CO₂(g) + H₂O(l)
Besides a measuring cylinder, which two pieces of apparatus are needed to obtain dry zinc sulfate crystals from the reaction mixture?
1 filter funnel
2 evaporating dish
3 gas syringe
4 thermometer
