Trioxocarbonates (IV)

Trioxocarbonate (iv) are salts derived from trioxocarbonate (iv) acid when it reacts with metals and metallic oxides.

All trioxocarbonate (iv) salts of Sodium (Na), Potassium (K) and Ammonium(NH₄⁺) are soluble while all others are insoluble.

Note: All trioxocarbonate (iv) salts decompose to release CO₂ when heated except that of Na and K.

Preparation of Soluble Trioxocarbonate (IV)

Soluble trioxocarbonate (iv) are prepared by bubbling carbon (iv) oxide through a solution of the corresponding alkali.

2KOH _(aq) + CO_2(g)   →   K₂CO_3(aq)  +   H₂O_(l)

It can also be prepared by heating the corresponding hydrogen trioxocarbonate (iv).
