Consider the following observations for 2 metals (B and D) and solutions for metal cations (A+ and D+):
When metal B is placed in an aqueous solution of A+, a dark residue forms on the metal.
When metal B is placed in an aqueous solution of D+, a dark residue forms on the metal.
When metal D is placed in an aqueous solution of A+, the
appearance of the metal does not change.
a. Rank the metals (A, B, and D) in terms of reducing agent
strength, from the strongest to the weakest.
b. Rank the metal ions (A+, B+, D+) in terms of oxidizing agent strength, from the strongest to the weakest.
Homework Answers
When metal B is placed in an aqueous solution of A+, a dark residue forms on the metal.
that means B is more reactive than A.
When metal B is placed in an aqueous solution of D+, a dark residue forms on the metal.
that means B is more reactive than D.
When metal D is placed in an aqueous solution of A+, the appearance of the metal does not change.
that means D is less reactive than A.
thus
increasing reactivity order: D < A < B
thus
a. Rank the metals (A, B, and D) in terms of reducing agent strength, from the strongest to the weakest: B > A > D
B is strongest and D is weakest reducing agent.
b. Rank the metal ions (A+, B+, D+) in terms of oxidizing agent strength, from the strongest to the weakest: D > A > B
D is strongest oxidizing agent and B is weakest oxidizing agent.

Substances A2, B2, and C2 can all act as oxidizing agents. In solution, A2 is green, B2 is yellow, and C2 is red. In the reactions in which they participate, they are reduced to A-, B-, and C ions, all of which are colorless. When a solution of B2 is mixed with one containing C ions, the color changes from yellow to red. a. Which species is oxidized? b. Which is reduced? When a solution of B2 is mixed with...

Consider a voltaic cell in which one half-cell is made of metal X immersed in an aqueous solution of X(NO3)2 and the other half-cell is made of metal Y immersed in an aqueous solution of Y(NO3)2. When the two half-cells were connected metal X was the cathode. From this we can conclude that metal X is more reactive than metal Y. metal Y is a stronger reducing agent than metal X. metal Y is a stronger oxidizing agent than metal...
