Interpretation: Each
Concept Introduction: Oxidation is the loss of electrons.
Reduction is the gain of electrons.
When oxidation and reduction simultaneously take place, then it is known as redox reaction.
In balanced redox reaction, each of the atom on both sides of reactions is equal.
To
1. Assign the oxidation states to all the atoms. Identify the substances that are being oxidized and reduced.
2. Separate the reaction into two half-reactions: oxidation half reaction and reduction half reaction.
3. Balance each of the half-reaction with respect to mass in the following order:
Balance all the elements other than
Balance
Balance
Balance the charges
4. Balance each of the half-reaction with respect to charge by adding the electrons to the right side of the oxidation half-reaction and the left side of the reduction half-reaction.
5. Multiply one or both half-reactions (if required) by a small whole-number so as to make sure the number of electrons in both half-reactions by a small whole number.
6. Add the two half reactions by cancelling electrons and other species (if required) to obtain a balanced chemical reaction.
7. Verify that the reaction is balanced with respect to both mass and charge.

- Consider the following galvanic cell: Calculate the concentrations of Ag+(aq) and Ni2+(aq) once the cell is dead.arrow_forwardFour metals, A, B, C, and D, exhibit the following properties: (a) Only A and C react with 1.0 M hydrochloric acid to give H2(g). (b) When C is added to solutions of the ions of the other metals, metallic B, D, and A are formed. (c) Metal D reduces Bn+ to give metallic B and Dn+. Based on this information, arrange the four metals in order of increasing ability to act as reducing agents.arrow_forwardWrite balanced equations for the following half-reactions.
