Document Summary

Must wear safety goggles and closed toe shoes in the lab. Use sodium bicarbonate to clean up acid. Boric acid is used for base spills, it can be found in the hoods. % yield = (crude mass- pure mass)/ crude mass x 100. Molarity = no. of moles / volume in l. % error = (actual value experimental)/actual value 100. 1 mmhg = 1 torr, 760 torr =1 atm. 13. 6 mm of h2o = 1 mm hg. Pw = pressure of h2o ( h/ 13. 6) Valency = atomic weight / equivalent weight. Equivalent weight can be found by dividing the atomic weight by the oxidation number. Kf = freezing point depression constant for the solvent. Grams of given substance x 1 mol / mw. Ha + h2o --> h3o+ + a- Ka is a constant given acid at a given temperature. Ph = pka + log [a-] / [ha] Solid > liquid > gas (least dense)
