Strong and Weak Acids and Bases

Strong and Weak Acids and Bases. Pg 560-578. The strength of an acid is determined by the extent to which it ionizes, its percent ionization, not the concentration of the acid, the concentration of its hydronium ions, or its ability to react with a metal. Strong Acid.

Limiting Reactants (Reagents)

Limiting Reactants (Reagents). and Percent Yield. Calculations need to be based on the limiting reactant. Example 1: Suppose a box contains 87 bolts, 110 washers and 99 nails. How many sets of 1 bolt, 2 washers and 1 nail can you use to create? What is the limiting factor?

An acid releases H + ions into water. An a cid is a proton donator.

An acid releases H + ions into water. An a cid is a proton donator. Broenstedt -Lowry definitions for acids and bases. A base releases OH - ions into water. A base is a proton acceptor. When HCl dissolves in water, it acts as an acid and donates a proton to the water.
