Phosphoric acid is a triprotic acid
WebOct 10, 2015 · Phosphoric acid (which is WEAK ACID) releases it's protons in 3 different stages. It has 3 pKa values for 3 dissociations. So it is impossible to get a 1:1 reaction , reactant condition when titrating. Here … WebAn acid that contains more than one ionizable proton is a polyprotic acid. These acids undergo stepwise ionization reactions involving the transfer of single protons. The ionization constants for polyprotic acids decrease with each subsequent step; these decreases typically are large enough to permit simple equilibrium calculations that treat ...
