Concept explainers
(a)
Interpretation:
The half equation method of balancing redox equation needs to be explained.
Concept introduction:
A redox reaction is the reaction in which one reactant gets oxidized and another reactant gets reduced.
On losing electron/s by reactant, it gets positively charged/negative charge decreases and undergoes oxidation. On the other hand, when a reactant gain electron/s, it undergoes reduction and gets negatively charged/positive charge decreases on it.
(b)
Interpretation:
Disproportionation reaction needs to be explained.
Concept introduction:
A redox reaction is the reaction consists of reactant in which one reactant gets oxidized and another reactant gets reduced.
On losing electron/s by reactant, it gets positively charged/negative charge decreases and undergoes oxidation. On the other hand, when a reactant gain electron/s, it undergoes reduction and gets negatively charged/positive charge decreases on it.
(c)
Interpretation:
The term titration needs to be explained.
Concept introduction:
A titration is the method in which a known solution which termed as titrant is added from a burette to a measured amount of unknown solution and titrated to complete the reaction.
The unknown solution usually kept in conical or titration flask. A solution with known concentration is required for the determination of unknown solution with its concentration.
Completion of the reaction indicated by change in color of solution.
(d)
Interpretation:
The standardization of a solution needs to be explained.

- Atomic masses can be determined by electrolysis. In one hour, a current of 0.600 A deposits 2.42 g of a certain metal, M, which is present in solution as M+ ions. What is the atomic mass of the metal?arrow_forwardThe following two half-reactions arc involved in a voltaic cell. At standard conditions, what species is produced at each electrode? Ag++eAgE=0.80VNi2++2eNiE=0.25Varrow_forwardIn some old European churches, the stained-glass windowshave so darkened from corrosion and age that hardly anylight comes through. Microprobe analysis showed that tinycracks anddefects on the glass surface were enriched ininsoluble Mn(III) and Mn(IV) compounds. From AppendixE, suggest a reducing agent and conditions that might successfullyconvert thesecompounds to soluble Mn(II) withoutsimultaneously reducing Fe(III) (which gives the glassits colors) to Fe(II). Take MnO2 as representative of theinsoluble Mn(III) and Mn(IV) compounds.arrow_forward

- (A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. An acidic and a basic solution may be used to balance the redox reaction when the oxidation number method is employed. The final step in balancing redox reactions using the oxidation number method is to balance by inspection. 2. In the oxidation number method of balancing redox reactions, there is a need to add water and hydroxide ions on both sides of the chemical reaction. The oxidation state of oxygen is always (-2) except for peroxides. 3. In the half-reaction method of balancing redox reactions, the reaction is divided into three half-reactions. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is an oxidizing agent. 4. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent.
