    I am trying to do my individual investigation for A level chemistry and im doing it on comparing different methods of analysing copper. One method i have chosen is a displacement reation between copper and zinc.I currently have

    1. Place the zinc in a beaker with excess copper solution.

    2. Allow time for the reaction to finish.

    3. Remove excess zinc with sulphuric acid.

    4. Filter

    5. Dry and weigh the copper.

    However, i do not know how toelaborate on this, how do i know how much zinc to use or how long it will take? If anyone has any help of links i will be very thankful.

    If you are trying to determine copper ions in solution your method will not work...

    You, yourself say "use excess copper sulphate solution"

    The zinc in this case is the limiting reagent...
