The chemical reactions:
CuSO4(aq) + Zn(s) → ZnSO4(aq) + Cu(s) Zn(s) + H2SO4(aq) → ZnSO4(aq)
+ H2(g) The copper on the surface quickly reacts with oxygen
according to the following reaction: 2Cu(s) + O2(g) → 2CuO(s)
Experimental Procedure Dissolve
completely about 0.5 to 0.7 g of copper (II) sulphate pentahydrate
in about 10 to 20 mL of deionized water. Calculate the amount of
zinc powder that must be added to a copper sulfate solution so that
the sulfate completely reacts....
