Document Summary
Water is a good solvent because it is a polar molecule. Water can also dissolve non-ionic compounds if they have polar bonds. How much of a substance will dissolve in a given amount of water. Varies greatly, but if they do dissolve the ions are separated and can move around. Substances that completely ionize when dissolved in water. Strong acids - dissociate completely to produce h+ in solution - hi, hclo4, hcl, hbr, Strong bases - react completely with water to give ions group 1 hydroxides, Substances that exhibit a small degree of ionization in water. Weak acids - dissociate to a slight extent to give h+ in solution any acid that is not strong. Weak bases - react only slightly with water to give. Oh ions any base that is not strong. Molarity (m) = moles of solute per volume of solution in liters:
