(a)

Interpretation Introduction

Interpretation:

Chemical reaction that can form PbOH+ has to be written and an experiment has to be proposed to measure its different concentration with pH meter.

Concept Introduction:

Mass balance equation represents net quantity of all such species in solution that have specific atoms must remain equal to total quantity of atoms added or delivered to the system initially.

For example, if 0.020 mol of acetic acid has been dissolved in 1 L solvent to form 0.020 M CH3COOH solution, then after dissolution, amount of unionized and ionized acetic acid must remain equal to 0.020 M.

  0.020 M=[CH3COO]+[CH3COOH]

For any systematic equilibrium, there might be more than one mass balance equations unlike charge balance equation. Such equations are governed by possible product species.

(b)

Interpretation Introduction

Interpretation:

A different method of determination for equilibrium constant of PbI+ has to be proposed.

Concept Introduction:

Refer to part (a).

Please draw the inverted chair forms of the products for the two equilibrium reactions shown below. Circle the equilibrium reaction that would have a AG = 0, i.e., the relative energy of the reactant (to the left of the equilibrium arrows) equals the relative energy of the product? [No requirement to show or do calculations.] CH3 CH3 HH CH3 1 -CH3
5. Please consider the Newman projection of tartaric acid drawn below as an eclipsed conformer (1). Please draw the most stable conformer and two intermediate energy conformers noting that staggered conformers are lower in energy than eclipsed forms even if the staggered conformers have gauche relationships between groups. [Draw the substituents H and OH on the front carbons and H, OH and CO₂H on the back carbons based on staggered forms. -CO₂H is larger than -OH.] OH COH ICOOH COOH COOH 1 2 COOH COOH 3 4 Staggered Staggered Staggered (most stable) Indicate the number of each conformer above (1, 2, 3 and 4) that corresponds to the relative energies below.
