9787240063 | common ion effect | if you have hydrochloric acid or something, if you add more chloride ions, it will shift equilibrium left and increase pH | 231 | |
9794286049 | buffers | add conjugate base/acid in system with its acid/base when add more H or OH, consumes some of buffer but the other thing is weak and doesn't change do ICE table where add amount of strong acid to neutral and subtract from cation | 232 | |
