(a)
Expert Solution
Interpretation Introduction
Interpretation:
The presence of a common ion is to be explained. The affect of the presence of a common ion on equilibrium of the given reaction is to be stated. The term used for an acid-base solution that contains a common ion is to be determined.
Concept introduction:
The presence of a common ion brings about a shift in the equilibrium position.
To determine: An explanation regarding the presence of a common ion.
Answer to Problem 1RQ
Answer
The presence of a common ion shifts the equilibrium position.
Explanation of Solution
Explanation
The shift in the equilibrium state that happens due to the addition of an ion that is already present in the equilibrium reaction is stated as the presence of a common ion.

Answer to Problem 1RQ
Answer
The presence of a common ion shifts the equilibrium of the given reaction towards left.
Explanation of Solution
Explanation
The given reaction is,
HNO2(aq)⇌H+(aq)+NO2−(aq)
The presence of a common ion in the given reaction will reduce the solubility of the given acid shifting the equilibrium towards the left. The dissociation of the given acid will be suppressed.

Answer to Problem 1RQ
Answer
An acid-base solution that contains a common ion is a buffer solution.
Explanation of Solution
Explanation
An acid-base solution that contains a common ion is a buffer solution.
A buffer solution is also defined as a solution that resists a change in the
pH on addition of an acid or an alkali
Conclusion
Conclusion
A solution that resists a change in the
pH on addition of an acid or an alkali is termed as a buffer solution

3. SYNTHESIS. Propose a sequence of synthetic steps (FGI) that convert the starting
material (SM) into the Target molecule. For each FGI in your proposed synthesis,
specify the reagents / conditions, and draw the product(s) of that FGI. DO NOT
INCLUDE the FGI mxn in the answer you submit. If an FGI requires two reagent
sets, specify the order in which the reagent sets are added, e.g., i) Hg(OAc)2 / H₂O;
ii) NaBH4/MeOH. Indicate the stereochemistry (if any) of the products of each FGI.
