- Precursor for important copper compounds such as copper (II) chloride
- Does occur naturally as rare mineral spertiniite
Soluble in ammonium hydroxide
- Completely dissolve 72g of hydrated copper (II) acetate (0.36M) in 1L of water.
- Completely dissolve 42g of hydrated sodium hydroxide (0.72M) in 50ml of water.
- Chill both solutions
- Combine solutions, keeping the temperature of the solution below 80°C, producing copper hydroxide and sodium acetate.
- Cu(CH3COO)2(aq) + 2 NaOH(aq) → Cu(OH)2(s) + NaCH3COO(aq)
