Redox Principles - Redox Reactions

1. Given the balanced equation, enter the formula and state of the product that formed as a result of the oxidation of its precursor (oxidation product). If more than one answer exists, separate by a comma.

3Mg(s) + 8HNO3(aq) 3Mg(NO3)2(aq) + 2NO(g) + 4H2O(l)

2. Given the unbalanced equation, indicate whether AuCl3(aq) accepts electrons (A), donates electrons (D), both (B) or neither (N). You may enter the abbreviation without parenthesis.

3Al(s) + 2AuCl3(aq) 2Au(s) + 3AlCl3(aq)

3. Given the balanced equation, enter the formula and state of the species that is oxidized. If more than one answer exists, separate by a comma.

3Mg(s) + 2AuCl3(aq) 2Au(s) + 3MgCl2(aq)

Explanation / Answer

1. Given the balanced equation, enter the formula and state of the product that formed as a result of the oxidation of its precursor (oxidation product). If more than one answer exists, separate by a comma.

3Mg(s) + 8HNO3(aq) 3Mg(NO3)2(aq) + 2NO(g) + 4H2O(l)

Solution :-

In the given equation Mg is oxidized from 0 to +2 oxidation state

The formula of the oxidized element is Mg(NO3)2(aq)

2. Given the unbalanced equation, indicate whether AuCl3(aq) accepts electrons (A), donates electrons (D), both (B) or neither (N). You may enter the abbreviation without parenthesis.

3Al(s) + 2AuCl3(aq) 2Au(s) + 3AlCl3(aq)

Solution :-

In the given equation the oxidation state of the Au is changed from +3 to 0 that means gained 3 electrons

So AuCl3 gained electrons.

3. Given the balanced equation, enter the formula and state of the species that is oxidized. If more than one answer exists, separate by a comma.

3Mg(s) + 2AuCl3(aq) 2Au(s) + 3MgCl2(aq)

Solution :-

In the given equation the Mg is oxidized from 0 to +2 oxidation state

Formula of the oxidized species is MgCl2(aq)
