Blue Fire Pointer S207 ISS Investigating the factor that affect electrolysis of saltwater and calcium carbonate: 3. Results

3. Results



The results of our experiment are as shown below:



Table 1: Results for the anode experiment.

Write up:
In the first experiment, we wanted to find out the best material for the anode which can increase the rate of electrolysis. The mass increase for the wire mesh in the Brass experiment was the most compared to the other anode materials. This is followed by Aluminium and then copper.

Table 2: Results for the temperature experiment

Write up:
In the second experiment, we wanted to find out the best temperature of the seawater which can increase the rate of electrolysis.  The mass increase for the wire mesh in the 20˚C seawater experiment was the most compared to the other seawater temperatures. This is followed by the 25˚C seawater and then the 15˚C one.

(Expt 1)

Write up: In the first experiment, we wanted to find out the best material for the anode which can increase the rate of electrolysis. In this table, it shows a graph of the mass gained of the wire mesh using the 3 different anode materials. From this graph, we could see that the mass gained by using the Brass anode was the most, followed by the Aluminium and then the copper.










Graph 2:  Graph of the weight  of the cathodes after the temperature experiment(Expt 2)

Write up:
In the second experiment, we wanted to find out the best temperature of the seawater which can increase the rate of electrolysis. In this table, it shows a graph of the mass gained of the wire mesh using the 3 different temperatures. From this graph, we could see that the mass gained by using 20˚C for the seawater was the most, followed by the 25˚C setup and then the 15˚C one.
