What is Ka2?

Postby Raymond_Guan_1H » Sat Dec 03, 2016 5:22 pm

I came across a question on one of the past midterms asking for a reaction that represents Ka2 for sulfurous acid (H2SO3). What exactly is Ka2?

Polyprotic acids (acids that have more than one proton to donate) will have Ka2 values. The Ka2 value describes the constant that you should use when the polyprotic acid is losing its second proton (H+).
