All required chemicals and solvents… 2677 Words 11 Pages is putting the chemical reactions to work! Everything has a purpose in the lab. Eventually, the two reactions occur at the same rate and the system reaches a state of equilibrium. The five general types of chemical reactions are synthesis also known as direct combination , decomposition, single replacement also known as single displacement , double replacement also known as double displacement , and combustion. Each section must be present in a complete report. Introduction Sodium chromate, Na2CrO4, is a crystallized powder or yellow crystals. Le Chatelier's principle can be stated as follows: A change in one of the variables that describe a system at equilibrium produces a shift in the position of the All observations were recorded as to the color changes and the number of drops added to initiate a change in color. The purpose of this lab was to understand equilibrium.

A net reaction will take place in some direction until a new equilibrium state is attained. In order to re-establish the equilibrium, the ions interact in such a way that the reaction quotient again becomes equal to the equilibrium constant. What does the Law of Chemical Equilibrium state? First is the Effect of Concentration on Equilibrium. To tube 3, add 5 drops of 1 M ammonium thiocyanate. To test this, dialysis tubes were submerged in different concentration fructose solutions.
