Reactions of metals and acids Reactions between most acids and metals follow a very similar pattern, making a ‘salt’ and hydrogen gas. We can show this pattern using a word equation for the reaction to represent the reactants (the acid and the metal) making the products (the salt [ and hydrogen):
Table of Acids with Ka and pKa Values* CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. The pKa values for organic acids can be found in Appendix II of Bruice 5th Ed.
TLDR; Is there a lookup table for the K_a values of acids and bases? I googled the K_a value of nitrous acid (HNO_2) and found all this: 4.6 x 10^-…
When pKa=pH, the acid base reaction is at equilibrium and you will have 50% acid form, 50% base form. The values of pKa and pH tell you how much the molecule and the solvent each “want” the proton.

ACIDS PRACTICE pK a and pK b © SMO SMOsNotes.com 1 Methanoic acid (HCOOH) is a weak acid with pK a =3.75. (a) Calculate the pH of a 0.100 mol dm-3 solution of methanoic acid. [3] K a = 10-3.75 = 1.78x10-4 HCOOH HCOO-+ H+ K a = [HCOO-][H+] = [H+]2 [HCOOH] 0.100 assuming dissociation of acid negligible compared to its conc.
Reactions of acids with metals: Worksheet 4.5.1 Making a salt Many metals can displace hydrogen from acids to form salts. An excess of the metal is added to make sure all the acid reacts. Then the excess metal is filtered out to leave a neutral solution. 1. What is the same about the formulae of these acids:
