CHEM 101 Lecture Notes - Lecture 4: Molar Concentration
Document Summary
A solution is a homogeneous mixture of how many substances? two or more. Dissociation-when an ionic substance dissolves in water, the solvent pulls the individual ions from the crystal and solvates them. Nonelectrolyte-does not dissociate into ions in water strong electrolyte-dissociates completely in water weak electrolyte-dissociates partially in water. A precipitate forms when mix ions that form an insoluble compound molecular equation-shows the complete formulas of all reactants and products complete ionic equation-reflects the species present in the reaction mixture net ionic equation-compounds that change during the reaction. Acids-substances that release h+ when dissolved in water. Bases-compounds that reduce the concentration of h+ in a solution. When solutions of an acid and base are combined, what usually forms? salt and water. When a carbonate or bicarbonate reacts with an acid, what usually forms? salt, carbon dioxide, and water. An oxidation occurs when an ion loses electrons.
