Purpose: The main purpose of our group planning session was to create phases at which we
would progress through this project. Along with that we set deadlines for when the phases woul
The purpose of this investigation is to test Le Chateliers principle by applying stresses to seven
different chemical equilibria, thereby gaining an innate understanding of the principle.

How can you make the reaction between Alka-Seltzer and water occur faster?
In order to increase the speed of the reaction rate of Alka-Seltzer and water, we will test two
separate input variables. The first variable we believe to incr

Chemical Systems in Equilibrium [part I] ANSWERS
Dynamic equilibrium involves a balance involving motion, in chemical
equilibrium a dynamic equilibrium occurs in which the rate of the forward
reaction equals the rate of the reverse reaction. Static equili
How will the pH be affected by significant changes in the chemicals concentration?
The pH of any solution is solely dependent upon the concentration of hydrogen ions that
are found in the solution. Thus pH stands for power o
To learn how to titrate solutions properly.
To standardizes a sodium hydroxide solution, and then use that standardized solution to determine the
actual molarity (concentration) of hydronium in a weak acid, ethanoic acid (vinegar diluted to a of
To experiment with a classic kinetics reaction, on order to find the significance of changing the initial
concentrations of three of the reacting species.
Within this reaction the rate determining step (slowest step) happens to be H 2
