Unformatted text preview: disconnected the circuit leaving a little time for more current to flow through. This would have resulted in a lower Faraday value than actual because the current would not be accounted for while the mass that moved would be. If the stirring bar was not on high enough, the solution could have become supersaturated leading to a layer of insulation could have formed on the electrodes causing the Faraday value to be higher that actual. There was some instrumental errors that are normal as far as equipment, such as ammeters only being able to be read to a certain level of accuracy and the analytical balance only being able to weigh masses accurately to +/- .0001grams....
