[Eng. Ahmed Said]

In an electroplating process taking place copper, by passing 1/2 faraday in aqueous solution of

gold(111) chloride(the platting occurs to one side only of area equals 100cm squer of copper

sheet).

a) Calculate the thickness of the deposited gold layer, given that the atomic mass of gold 196.98

and its density13.2 gram/cm aqup

b)Write the chemical reaction taking place at the two electrodes
