Electrolysis and Concentration

C3 Electrolysis and the Concentration Concentration of the solution (in g/dm3)| Current (in amps)| fairish Results| | 1st savour| second try| 3rd try| | 8| 0.54| 0.48| 0.57| 0.555| 12| 0.63| 0.66| 0.64| 0.635| 16| 0.84| 0.81| 0.85| 0.845| 20| 0.92| 1.1| 1.04| 1.07| 24| 1.34| 1.15| 1.62| 1.245| shutdown My graph has a positive correlation. I can regain from my table that the higher the concentration, the higher the veritable. in the beginning I plotted my intermediate results, I make accredited that I identified the anomalies, by seeing which one stands forth from the rest. I see the pattern because when it was 8 on average of 0.555 and and then at 16 it was 0.845, this shows the test went well because it change order each time. The covariants in this experiment are the concentration of solution. My results impart be reliable because I carried it out 3 times. The covariant I will change is the concentration of the solution. My line of scoop up fi t shows the positive correlation. I used a gentle range of concentrations so that the experiment was valid. Also I do sure the pattern in my results was correct. at that place were alike limitations in this experiment. The first being making sure I suppose the highest possible reading. This was quite concentrated because the readings went down actually quickly.

another(prenominal) limitation was keeping the anode and cathode separate, so that it wouldnt change the reading. This was operose because they are close together. The higher the concentration of the solution, the higher the current. This carriage that a high concentration solution has more ions. in that respect ar e more ions discharging meaning there is a s! tronger current. Anode - 4OH 4e ----- O + 2H O Negative hydrogen ions are attracted to the anode, where they lose electrons and became atomic number 8 and water. Cathode + 2H + 2e ----- H autocratic hydroxide ions are attracted to cathode, where they gain electrons and frame hydrogen. How voltage affects the current: Use the same...If you want to get a full essay, regulate it on our website: OrderEssay.net
