Preparation of Copper(I) Chloride
Reactions:
1) Cu(S) + 4HNO₃(aq) ->Cu(NO₃)₂(aq) + 2NO₂(g) +2H₂O(l)
2) 2HNO₃(aq) + Na₂CO₃(s) ->H₂O(l) + CO₂(g) + 2NaNO₃(aq)
3)Cu(NO₃)2(aq) + Na₂CO₃(s)-> CuCO₃(s) + 2NANO3(aq)
4)CuCO_3(s) + 2HCL(aq) -> CuCl_2(aq) +H₂O_(l) + CO_2(g)
5)CuCl₂(aq) + Cu(s) -> 2CuCl(s)
Report:
Weight of Copper: 1.004g
Volume of Added Nitric Acid: 4.9mL
Total weight of added Sodium Carbonate: 3.841g
Weight of watch glass and filter paper: 51.740g
Weight of watch glass, filter paper, and CuCl Precipitate:53.513g
Experimental Yield of CuCl: 1.775g
Theoretical Yield of CuCl: 3.55g
Percent Yield of CuCl: 50%
Could we use HCl to dissolve the copper metal instead of nitricacid in the first reaction? Please explain.
