Question

5. Mg + CuCl2(aq)
Mg is more reactive than copper and hence reacts with aqueous
Copper chloride.
a. Based on that information complete the above equation and balance it.
b. Identify the type of reaction.
c. Which reactant is oxidized and which is the oxidizing agent?
d. Is the reverse of this reaction also possible? Give the reason for your answer.
e. Copper chloride solution is blue in colour. Predict how the colour will change after the reaction.

Answer 1

Answer:

a) Mg + CuCl2-----> MgCl2 + Cu

b) Single displacement reaction

c) Mg is oxidised and CuCl2 is an oxidizing agent

d) No the reverse reaction is not possible Because Cu is less reactive than Mg

e) MgCl2 forms colourless solution. Thus solution will turn into colourless.
