Chemical Properties of CO2

1.It undergoes reduction to form carbon (ii) oxide in the presence of coke

CO₂ (g) +C(g)  →  2CO(g)

2. It dissolves in water to form trixocarbonate (iv) acids

CO₂(g) +H2O(L)  →   H₂CO₃(ag)

3. It readily reacts with alkalis to form trioxocaioeate (iv) salts

CO₂(g) +2NaON(ag)    →   Na CO₃(ag) + H₂O(L)

4. it reacts with burning magnesium

CO₂(g) + Mg(S)  →   MgO(S) + C(S)
