| Question | Answer |
| Beer's law | A=e[C]l Works for all wavelengths, but works best at lambda max |
| Molarity (M) | (moles solute)/(volume solution) |
| Molality (m) | (moles solute)/(kg solvent) |
| Mass Percent | (mass solute)*100/(mass solution) |
| Density | (mass solution)/(volume solution) |
| Dilution formula | MiVi = MfVf |
| Dilution by 10 | 1 part solute, 9 parts solvent |
| Soluble | - Group IA, NH4+ - Nitrate NO3- - Cl-, Br-, I- (except Ag+ and Pb2+) - Sulfate SO4(2-) (except Ba2+, Pb2+, Hg2+, Ca2+) |
| Insoluble | - Carbonate (CO3[2-]), Chromate (CrO4[2-]), Phosphate (PO4[3-]), Sulfide (S2-), Hydroxide (OH-) |
| Oxidation state rules | O: -2 (-1 in peroxides) H: +1 Halogens: -1 Alkali metals: +1 |
| Oxidation | Loss of electrons (oxdidation state goes up) |
| Reduction | Gain of electrons (oxidation state goes down) |
| Intensive | Does not depend on amount |
| Extensive | Depends on amount |
