Factors Affecting Chemical Equilibrium
What Factors Affect Chemical Equilibrium?
Introduction:
In investigation 14, “What Factors Affect Chemical Equilibrium?”, the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents with the Iron Thiocyanate and changing the temperature, a new equilibrium was reached and the color changes were recorded.
Experimental:
Materials Used:
1 M Fe(NO3)3 (aq)
1 M NH4NCS (aq)
0.10 M SnCl2 (aq)
0.1 M AfNO3 (aq)
1 M Na2HPO4 (aq)
1 M NH3 (aq)
H2O
Bunsen burner
Ice
Test tubes
Beakers
Pipets
First, Iron Thiocyanate (FeNCS) was formed by adding 8 drops of Iron Nitrate [1 M Fe(NO3)3 (aq)] and eight drops of ammonium thiocyanate [1 M NH4NCS (aq)] to 100 mL of H2O. After the deep red solution, FeNCS, was created, the solution was divided into eight different test tubes and two separate beakers. Then, each of the reagents listed above was added individually to each test tube. The color change was observed, and the results were entered into the data table. Once all eight test tube had the reagents added and the data recorded, the beaker of FeNCS solution was put on a bunsen burner at 60୦ C. The color was also observed and recorded in the data table. The final beaker was stuck into a container of ice, and the color change was observed. Each group added their data to a data chart to compare the results.
Results:
Reagent Color Changes of All Groups
D = darker
L= lighter
Equation used to create the red solution:
H2O + Fe(NO3)3 + NH4NCS FeNCS
Conclusion:
All of the objectives of the investigation were accomplished during this experiment. The results demonstrated that if the reagent added
