Day 21: Making the new solution in preparation for electrodeposition
The testing of the pH is as follows:
Initial PH is 3.70 After 140 drops of NaOH after the initial 48 drops That was put in the pH for the 3 to 1 solution was 8.01
Initial pH is 3.13 After 450 drops of NaOH after the initial 48 drops that was put in the pH for the 6 to 1 solution was 8.10
Each were heated for 2 minutes and 30 seconds and a slight color change was produced. Then we went to test the pH of the solutions after they had been heated to ensure stability of the pH.
The pH after the 3 to 1 was heated was 6.44 so it decreased... so an additional 30 drops was added and the pH was now 9.05
The pH after the 6 to 1 was heated was 5.62 so it decreased...so an additional 80 drops was added and the pH was now 8.38
We also made 21 electrodes.
