# PKa and equilibrium constant values

Not what you're looking for? Search our solutions OR ask your own Custom question.

I have the following problem: the pKa values for H2SeO3 at 25 degrees C are 2.64 and 8.27. Write the base hydrolysis equilibrium equations for SeO3^2-(aq) and HSeO3 ^- (aq) ions, and calculate the equlibrium constant values for each equilibrium.

I think that I am completely stuck on how to approach this equation. Please help!
