time for all specimen. Observation Basis of test The initial blue colouration of the mixture turns green‚ then yellowish and may finally form a brick-red precipitate. Benedict’s solution contains copper sulphate. Reducing sugars reduce soluble blue copper sulphate‚ containing Cu2+ to insoluble red-brown copper oxide‚ containing Cu+. The latter is seen as a precipitate. Note: 1) Read the colour

will pull the nitrate compound from the lead and the carbonate will be forced to bond with the lead. Part 4: I believe that a single displacement reaction will occur when copper (11) sulphate and magnesium are mixed because on the activity series magnesium is more reactive than copper and will therefore pull the sulphate away and bond with it. Part 5: I believe that a single displacement reaction will occur when silver nitrate and copper are mixed because on the activity series copper is more reactive
