Recommended Posts

i did an experiment on electrolysis on various substances. two substances were copper sulpahte which gave an ammeter reading of 0.87A and sodium chloride which gave an ammeter reading of 1.25A. i have a question which says.... suggest a reason why copper (II) sulphate and sodium chloride do not give the same ammeter readings.

 

i would appreciate your help. thanks in advance

Are the concentrations of the solutions the same?

Also, in copper sulfate the ions have two units of charge, which makes discharging the ions slower. The ions in copper sulfate (esp. the sulfate ion) also are larger, which makes them less mobile.
