Alka-Seltzer is a medication that works as an antacid and a pain reliever.
It contains NaHCO3 (baking soda) and H3C6H5O7 (citric acid). The two
reactants produce this relief through reactions between t

CHM152 Equilibrium helpful hint
All reactions are reversible, meaning they go forward as well as backward at least to
some extent, products changing back into reactants and vice-versa. Although it appears that a
reaction has stopped, in reality the rate i
CHM152 Kinetics helpful hint
One of the more difficult concepts in kinetics is reaction orders. You must know zero,
first, and second order reactions, their rate laws (equation), the corresponding integrated
formulas (in calculus its the integral of the e
Titrations of bases by acids can be graphed with volume of titrant versus
the pH. The equivalence point is where the base is neutralized but is not
always at a pH of 7. This point can be seen on the graph.
a. Background Information
The rate of a reaction is defined as the rate of change in relation to time of
the concentration of one of the reactants or products.
The purpose of this lab is to measure the rate of a physica

Le Chateliers Principle states that if a stress is applied to a system, such

In acid-base equilibria, some substances can act as either an acid or a base.
The equilibrium can be shifted by the pH. This is primarily done through
the [H+](aq) or [OH-](aq).

a. Background Information
The majority of acids and bases are actually weak acids and bases.
Therefore, if you know the molarity of the weak acid or weak base and
can measure its pH, you can calculate its Ka or Kb.
Gibbs free energy, denoted by G, is the amount of useful energy
available to do something. The change in G (G) can be used to
determine the spontaneity of a reaction or the likelihood that a reaction
