A constant current flowed for 2 hours through a potassium iodide solution oxidising the iodide ion to iodine (2I^(-) rarr I_(2) + 2e^(-)). At the end of the experiment, the iodine was titrated with 21.75 mL of 0.0831 M soldium thiosulphate solution. (I_(2) + 2S_(2)O_(3)^(2-) rarr 2I^(-) +S_(4) O_(6)^(2-)) What was the average rate of current flow in apmeres ? |
