Uses

Justification Questioned

Other

• Precursor for important copper compounds such as copper (II) chloride

Natural occurrence

• rarely occurring mineral spertiniite

Character

Soluble in ammonium hydroxide

Production

Synthesis

Combine a soluble copper (II) salt (like copper (II) chloride or copper (II) acetate) with sodium hydroxide or potassium hydroxide

1. Combine 50gcopper (II) acetate monohydrate (¼M) with 20g sodium hydroxide (½M), producing copper hydroxide and sodium acetate.
