1) dissociate into ions; these are called salts 2) non-electrolytes: insoluble, molecular (sugar) 3) weak electrolytes : small fraction dissociates NaCl in H2O at 20 degrees Celcius: max dissolved is 6 M Ba SO4: insoluble, 10^-5 M Precipitation reactions: Methathesis reaction: AB + CD AD + CB Table 5.1 Arrhenius acid/base concepts Scid = substance that when dissolved in water produces H+ aqueous Base = substance dissolved in water that produces OH- aqueous

Unformatted text preview: Acid + base a “salt” + water Fe(OH)2 + 2 HCl (aq) FeCl2 (aq) + 2 H2O Oxidation-Reaction Algebraic: going pup in oxidation state = oxudation; going down = reduction KMnO4 (aq) + HCl (aq) MnCl2 (aw) + Cl2 (aq) + KCl(aq) K+ + MnO- + H+ + Cl - Mn+2 + 2Cl- + Cl2 (g) + K+ + Cl-1) balance NON Oxygen and Hydrogen species 2) balance O by adding H2P to where needed 3) balance H by adding H+ 4) balance charge by adding e-...
