Carbonic acid, H2CO3 , has two acidic hydrogens. A solution containing an unknown concentration of carbonic acid is titrated with potassium hydroxide. It requires 24.2 mL of 3.940 M KOH solution to titrate both acidic protons in 54.1 mL of the carbonic acid solution. Write a balanced net ionic equation for the neutralization reaction. Include physical states.
