    In question 20 i thought it was supposed to be silver anode cause you indicated silver spoons in the questions

      Kindly note that the industry specializes in manufacturing silver spoons, which implies the silver must be pure. Oxidation takes place at the anode which is positively charged electrode. However, since the electrolyte is already soluble silver salt, where there is going to be migration of ions from the anode to the cathode, the anode is going to be an impure rod, hence any rod can be at the anode. This will allow for the Redox reaction and a pure silver spoon would be produced eventually.
      I hope this helps.

      In addition, in the electrolysis of silver metal, any rod can be used at the anode because the anode bar gradually dissolves to replenish the silver ions in the solution. The net result is that silver metal has been transferred from the anode to the cathode.
      Any type of rod can be used at the anode, the spoon has to be cathode since we must obtain a pure silver spoon while the electrolyte must be a soluble silver salt because it allows easy deposition of metal ions as a pure metal on the cathode.

    Okay sir how are u going to solve dis with all dis calculations on d day of exam
    Or u pick the parameters nd just do the calculation

      Try to set your time as your practice, do it over and over again until you get to solve multiple questions before time.
