Developing an Activity Series Activity 1 Data Table

Observations for Activity Series (Fill in data table)

	Observation (record yes or no if a reaction occurred)
	Mg2+(MgSO4)	Fe2+(FeSO4)	Cu2+(CuSO4)
Mg(s)	X	Yes	yes
Fe(s)	no	X	no
Cu(s)	Yes	no	X

1. For each combination from the above Developing an Activity Series Activity 1 Data Table where you saw a reaction, write the overall oxidation-reduction equation. (Hint each yes is an equation)
2. Based on the spontaneous equations you wrote for question number 1, place the metals in order from highest reduction potential to lowest reduction potential. (Hint look at equations reduction potentials)

Answer 1

solution Mg Cs) + Feso a caq) MgSO4 (aq) ters) In this reaction, Mg metal displaces fe from its aqueous solution je Mg metal gets oxidised whereas Feet gets reduced to reduced to fe metal. Thus, can say that the reduction potential of Fe ( Efetife) is greater than the réduction potentia of mg ( Emgeti mg) We
