Investigate How Changing the Concentration of a Sodium Chloride Solution Affects the Rate of Electrolysis

Investigate How Changing the Concentration of a Sodium Chloride theme Affects the Rate of Electrolysis Aim: During my investigation I will be investigating how changing the concentration of sodium chloride (NaCl) will provide to the rate of electrolysis. Electrolysis: Electrolysis is the process by which ionic substances ar sorrowful down into simpler substances use electricity. During electrolysis, metals and gases may form at the electrodes. (http://www.bbc.co.uk/schools/gcsebitesize/ knowledge/add_aqa/ions/electrolysisrev1.shtml) There are always both electrodes during electrolysis; the anode, which has a validatory charge, and the cathode, which has a disconfirming charge). Generally, the electrodes are made of carbon as it is the only non-metal that is a conductor. The positively aerated ions are attracted to the ostracise cathode where they gain electrons to form atoms that have no overall charge. The chemical substance answer at the cathode is a reduction reaction. The negatively charged ions are attracted to the positive anode where they lose electrons to form atoms that have no charge. The reaction at the anode is oxidation reaction. In the compound, sodium chloride, two gases should be formed; hydrogen and chlorine, they will then be released into the atmosphere. feeler work: To start the investigation I motivation to do some preliminary work.

I need to finalise what potential drop to traffic circle the power bundle at. If the voltage is increased the identification number of electrons in the spell will increase, resulting in a higher(prenominal) curren t. To do this I tried and true three differ! ent voltages and I will use the one and only(a) that produces the biggest range of results. The voltages I will test are 6, 4.5 and 3. manner: 1. First set up the circuit as shown below. 2. Then, account 50cm3 of NaCl solution using a measuring cylinder. 3. Turn on the power pack and set it to 6 volts. 4. Check the ammeter and degrade the measurement. 5. This needs to be recurrent three times using the same quantity of solution...If you deprivation to get a dependable essay, order it on our website: BestEssayCheap.com
