what was the answer of the last part in the last question that was that " how we could get more mass of silver deposited on cathode "
The answer was : USE A ANODE MADE OF SILVER :)

thanks usama but there would be many answers to this question

i wrote use of molten silver nitrate instead to aq. silver nitrate

by using molten silver nitrate the ions of silver would increase so more would develope on cathode


the font with the blue one i didint wrote in exam
i only wrote the red font part
yeah...i hope so :)

is my answer correct :/

By increasing current i think u would only increase the rate at which silver is deposited, not the amount


excatly , that would not increase the mass of silver deposited on cathode :)

PALS,rose and usama answers seems to be sensible and would be given credit :)
thnx :) :) :)

@ PRINCE ::: fifth MCQ was only the first two metals because copper doesn't react with HCI
