Why are all the orbitals that have the same principal number in Hydrogen degenerate? It is a triprotic acid, meaning it can donate 3 hydrogen ions successively with each reaction (we'll explore more into this as we go) and is a relatively weak acid since its degree of ionisation is not 100% ie. 1.4 * 10^(-4) All you have to do in order to find the value of the acid dissociation constant, K_a, is to write a balanced chemical equation for the equilibrium that is established when lactic acid, "HC"_3"H"_5"O"_3, is added to water.
