Question

Carbonic acid, H2CO3, has two acidic hydrogens. A solution containing an unknown concentration of carbonic acid is titrated with potassium hydroxide. It requires 25.9 mL of 4.670 M KOH solution to titrate both acidic protons in 56.5 mL of the carbonic acid solution. Write a balanced net ionic equation for the neutralization reaction. Include physical states.
