Day 4 - Trial 4

14/5/13

This time, we are changing the NaCl solution to Ethanoic acid to see if it speeds up the rate of reaction in generating electricity.

The first test (refer to Fig 9 and Fig 10) is with 100ml of Ethanoic acid (1M), the second test (refer to Fig 11 and Fig 9) is with 100ml of Ethanoic acid (2M)

Fig 11

We had to do 2 runs for the ethanoic acid with concentration of (2M) as the value of electricity being generated was fluctuating greatly. 

From this experiment, we can conclude that ethanoic acid does increase the speed of reaction, thus we will be replacing the 100ml of sodium chloride solution with ethanoic acid of concentration (1M).
