Synthesis
Combine a soluble copper (II) salt (like copper (II) chloride or copper (II) acetate) with sodium hydroxide or potassium hydroxide
- Combine 90ubm copper (II) acetate (½ M) with 40ubm sodium hydroxide (1M), producing copper hydroxide and sodium acetate.
- Cu(CH3COO)2(aq) + 2 NaOH → Cu(OH)2(s) + NaCH3COO(aq)
