Question

Write net equations for the spontaneous redox reactions that occur during the following or none if there is no extensive reaction.

Instructions:

Reactants Rxn: Ox(1) + Red(2) + other -> Red(1) + Ox(2) + other Iron metal is dipped into a NiSO4 solution Lead metal is placed in hydrochloric acid A silver wire is added to nitric acid Sodium metal is added to water A silver wire is placed into an acidified solution of KMnO4 Enter all substances in the order listed at the top of the column. Use a carot to indicate a superscript, but do nothing for subscripts. Use a hyphen + greater than (->) for yields. Click on the eye symbol to check your formatting.

Explanation / Answer

For WebAssign:

a) Iron metal is dipped into a Ni2+ solution
Ni^2+ (Coeff Ox1) + Fe (Coeff Red2) -> Ni (Coeff Red1) + Fe^2+ (Coeff Ox2)

b) Copper metal is added to hydrochloric acid
Does not react. (answer: none, none, none, none)

c) A silver wire is added to nitric acid (HNO3)
NO3^1- (Coeff Ox1) + 3Ag (Coeff Red2) + 4H^1+ (Coeff Other) -> NO (Coeff Red1) + 3Ag^1+ (Coeff Ox2) + 2H2O (Coeff Other)

d) Magnesium metal is added to water
2H2O + Mg -> H2 + Mg^2+ + 2OH^1-

e) Chromium metal is added to a solution of Mg2+
Does not react (answer: none, none, none, none)
