Write the precipitation reaction for cobalt(II) acetate in aqueous solution and indicate the state of matter.

Is cobalt(II) acetate considered soluble or not soluble ? ...
... A. Soluble
... B. Not soluble

Explanation / Answer

1)

Cu(CH3COO)2 (aq) + 2H2O(aq) ------------- Cu(OH)2 (aq) + 2CH3COOH (aq)

A copper(II) acetate is considered to be soluble in water

2) A

Since the reaction proceeds with a mixture that contains mostly products, K is greater than 1

3) Co(CH3COO)2 (aq) + 2H2O (aq)------------------- Co(OH)2 (aq)+ 2CH3COOH(aq)

A Cobalt(II) acetate soluble in water
