Document Summary

Synthesis of copper compounds form metallic compounds: cu cu(no3)2 cu(oh)2 cuo cuso4 5h2o cu. Synthesis of copper (ii) nitrate and copper (ii) hydroxide: cu(s) + 4no3(aq) cu(no3)2(aq) + 2no2(g) +2h2o(l, cu(no3)2(aq) + 2naoh(aq) cu(oh)2(s) + 2nano3(aq) Synthesis of copper (ii) oxide: cu(oh)2(aq) cuo(s) + h2o(l) Synthesis of copper (ii) sulphate: cuo(s) + h2so4(aq) cuso4(aq) + h2o(l) Recovery of copper: cuso4(aq) + zn(s) cu(s) + znso4(aq, zn(s) + 2hcl(aq) Percent recovery: ( initial mass / recovered mass ) x 100% Experimental procedure: part 1: synthesis of copper (ii) nitrate and copper (ii) Obtain an length of copper wire and a piece of sandpaper, sand wire and weigh on analytical balance. Place copper wire in beaker in fume hood with 10 ml of. Nitric acid, let wire dissolve, bright blue solution. Dilute with 25ml of deionized water, stir in 25ml of. 20% naoh: part 2: synthesis of copper (ii) oxide.
