Why does the blue disappear with copper chloride and zinc? Explanation: Zinc metal is oxidized to Zn2+ , whereas Cu2+ (as cupric chloride) is reduced to copper metal. A zinc electrode placed in a blue solution of Cu2+(aq) would rapidly acquire a copper coating, meanwhile the colour of the solution would fade as the copper precipitates.
Why does the blue color disappear in the reaction between copper sulfate and zinc? When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
What causes the color to fade in the blue solution? However, no copper ions enters in the electrolyte from anode. Thus concentration of copper ions goes on decreasing. This result in fading of blue colour. When copper ions completely finish the electrolyte becomes colourless.
What happens when you add zinc to copper chloride? The atoms of the more reactive metal push their electrons on to the ions of the less reactive metal. This reaction is an exothermic reaction. This is because copper is being formed during the reaction, meaning that new bonds are being formed.
