Question

Connect to negative pole Connect to positive pole Graphite Post 5-cent coin 6 M HCI Figure 2. Illustration of experimental set-up. 9. Complete the table beiow and ask for your instructor's approval before making the actual electrical connects. The electrodes must be connected to the battery so that the COIN WILL BE OXIDIZED, CAUTION: if the electrodes are not correct, formation of toxic Cl2 gas will resultl Chiorine gas is easly detected by its strong odor. Will this electrode be the Attach to the Positive or Cathode or Anode in the Negative pole of the electrolysis? Electrode battery? Nickel (5-cent coin) Graphite Post

Explanation / Answer

Answer

Electrode will this electrode be the cathode Attach to the positive or

or anode in the electrolysis negative pole of the battery

Nickel (5-cent coin) Anode positive pole of battery

Graphite post Cathode Negative pole of Battery

a) In electrolysis, oxidation takes place at anode while reduction takes place at a cathode. So in our case nickel (5-cent coin) get oxidized therefore we will use nickel (5-cent coin) as an anode and graphite post as a cathode.

b) As we know that electrons are negatively charged and it always flows toward positive terminal. therefore we will attach anode to a positive terminal of a battery to make a current pass in opposite direction of an electron flow. if we attached to the anode to a negative terminal of a battery than nickel (5-cent coin) will not get oxidized.

Hey, if you have any doubt feel free to ask and if you like lesson please give thumbs up. thanks!
