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)
