Particle size is directly proportional to relative supersaturation

Particle size remains constant regardless of relative supersaturation

Particle size is not affected by relative supersaturation

Particle size is inversely proportional to relative supersaturation (correct)

Increase the rate of nucleation

Use a higher degree of supersaturation

Maximize contamination

Minimize the degree of supersaturation (correct)

(Q + S)/S (Q = Concentration of mixed reagents before precipitation, S = solubility of the precipitate at equilibrium)

(S + Q)/S (Q = Concentration of mixed reagents before precipitation, S = solubility of the precipitate at equilibrium)

(S − Q)/S (Q = Concentration of mixed reagents before precipitation, S = solubility of the precipitate at equilibrium)

(Q − S)/S (Q = Concentration of mixed reagents before precipitation, S = solubility of the precipitate at equilibrium) (correct)
