# How to predict the products of the reaction of CO2(g) + KOH(aq)?

Well, $C {O}_{2} \left(g\right)$ is an $\text{acidic oxide}$ that reacts with bases......
$C {O}_{2} \left(g\right) + K O H \left(a q\right) \rightarrow {K}^{+} H C {O}_{3}^{-}$
${K}^{+} H C {O}_{3}^{-} + K O H \left(a q\right) \rightarrow {K}_{2}^{+} C {O}_{3}^{2 -}$
