Step | Data | Trial1 | Trial2 |
4 | Time (seconds) for color change | 08.21 | 07.28 |
4 | Notes for color change | The starting color of the solution is pink and after that it’schanged to Yellow | |
5 | Color change (if any) after one(1) drop of dilute ammonia | none | none |
6 | Time (seconds) for color tochange back | 27.56 | 28.93 |
7 | Number of drops for color tochange back | 4 | 5 |
1. What does the number of drops of ammonia water indicate? Inother words, what is their significance, such as if they were thesame for all trials or if they differed?
2.Explain chemically why you could not repeat the stepindefinitely.
3, Using Le Chatelier's Principle, discuss and explain yourresults for when you altered the procedure.
