How do you calculate the ph

WebSep 8, 2006 · 1. Sodium Chloride is a strong electrolyte meaning it will disassociate completely in solution. Strong electrolytes will not affect the pH of the solution as the acids / bases they form are also strong electrolytes. A NaCl solution of any concentration should have (ideally) a pH of 7. NaCl (aq) + H2O (l) ---> HCl (aq) + NaOH (aq) WebHow would I be able to calculate the pH of a buffer that includes a polyprotic acid and its conjugate base? For example, if I were to add a certain amount of the polyprotic acid H2A and a certain amount of its conj base A^2- (obviously in the form of a salt, say Na2A), how would I find the pH? Assume I know the ka1 and ka2 values. Now what?
