Electrolysis of Copper Sulfate Flashcards
1
Q
How can you find change in mass?
A
Weighing the electrodes on the weighing scale.
2
Q
What’s step 1?
A
Set the current to 0.2A and the time to 0.
3
Q
What’s step 2?
A
Weigh the electrodes and record the initial masses.
4
Q
What’s step 3?
A
Set the time to 20mins and reweigh the electrodes. Record the final masses.
5
Q
What’s step 4?
A
Repeat steps 1 to 3 for a range of currents( 0.3A, 0.4A, 0.5A)
