Question

What is the net ionic equation for the reaction of aqueous nickel(II) acetate and aqueous sodium carbonate?

Answer 1

Nickel (II) acetate is Ni (CH3COO)₂

sodium carbonate is Na₂CO₃

the reaction goes as follows:

Ni (CH3COO)₂ (aq) + Na₂CO₃ (aq) ===== NiCO₃ + 2 CH₃COONa (aq)

the ionic equation considers the species with the form of ions so:

Ni⁺² (aq) + 2 (CH3COO) (aq) +2 Na⁺ (aq)+ CO₃^-2 (aq) ===== NiCO₃ (s) + 2 CH₃COO^- (aq) + 2Na⁺ (aq)

now remove expected ions, the ones that appear on both sides of the equation:

Ni⁺² (aq) + CO₃^-2 (aq) ===== NiCO₃(s)

the solid compunds are not splitted
