## Question:

Write a net ionic equation for the overall reaction that occurs when aqueous solutions of potassium hydroxide and oxalic acid ({eq}\mathrm{H2C2O4} {/eq}) are combined.

## Chemical Equations :

Like math, a chemical equation is relatively used to express a chemical reaction in theory. A group of reactants at a definite proportion and composition react with a different group of reactants to form products and by-products in a chemical reaction.

To write the net ionic equation or the overall reaction that occurs when aqueous solutions of potassium hydroxide and oxalic acid.

The reaction between potassium hydroxide and oxalic acid looks like:

{eq}H_2C_2O_4(aq) + 2KOH(aq) \longrightarrow K_2C_2O_4(aq) + 2H_2O(l) {/eq}

The total ionic equation will be:

{eq}H_2C_2O_4(aq) + 2K^+(aq) + 2OH^-(aq) \longrightarrow 2K^+(aq) + C_2O_4^{2-}(aq) + 2H_2O(l) {/eq}

The net ionic equation is obtained by canceling and reducing the ions, which is:

{eq}H_2C_2O_4(aq) + 2OH^-(aq) \longrightarrow C_2O_4^{2-}(aq) + 2H_2O(l) {/eq}
