During yesterday's review session, we discovered that the pH formulas were missing from the marked-up legal cheatsheet Reference Table that you should be marking up so that you can do so by rote on your actual Regents Reference Table.

Here are the two formulas; put them by the acid-base titration formula:

1) -log[H+] = pH or -log[H3O+]= pH H3O+ is hydronium;
H+ is hydrogen ion

2) 10^-pH = [H3O+] = [H+]
(means " ten to the negative of the pH value equals the concentration or Molarity of
hydronium or hydrogen ion")
