    I'm doing Chemistry ISA next week and the question is 'Investigate a factor that may affect the mass of metal deposited on the negative electrode using electrolysis' I am using the independent variable of Current/Voltage. What method should i use? and where could i find further research on the method? I'm really stuck so any help would be great!

    If the voltage is too low, nothing will deposit. If the voltage is right, amount will depend on the charge (current*time).
