Document Summary

Solutions: defined as a homogeneous mixture of two or more pure substances. Solvent: is present in greatest abundance ; the majority component. All other substances are solutes; the minority component. Measure out the mass that you need from the molarity. Most ionic compounds dissociate into independent ions when dissolved in water. Electrolytes: the compounds that freely dissociate into independent ions in aqueous solution. Those aqueous solutions are capable of conducting an electrical current. Dissociation/solvation: when an ionic substance dissolves in water, the solvent pulls the individual ions from the crystal and solvates them. The polar nature of water with a partial negative charged end and partial positively charged end. The water molecules try to pull the sodium ion out from the clump of nacl molecule and creates a barrier around that ion. Motion of ions in solution is responsible for the conductivity of aqueous solutions solutions.
