Abstract for Lecture #10 - (a) Aqueous Solutions and (b) Molarity and Solution Stoichiometry


When an ionic compound dissolves in water, the ions dissociate and are solvated by water molecules. The solution then conducts electricity. An important part of solubility in water involves hydrogen bonds.

When solutions of ionic reactants are mixed, a reaction occurs only if a product forms that removes ions from the solution. Precipitation reactions occur when an insoluble ionic compound forms. Neutralization reactions take place when an acid and base combine to form a water molecule.
