What factor(s) affect the solubility of a slightly soluble salt? Choose all correct answers.
Particle size
pH
Formation of complex ions
The presence of uncommon ions
Temperature
The presence of oxygen gas
The amount of undissolved solid present
The presence of a common ion
Homework Answers
Solubility of sparingly soluble salts depends on
1. Temperature - as the temperature increases, solubility also increases.
2. Presence of common ion - presence of common ion in the saturated solution shifts the equilibrium to left. Thus crystallization is more. Solubility is less.
3. Particle size - smaller the particle size, greater is it's solubility.
4. pH change can also results in change in the solubility of the solute.

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...

Group I Cations A INTRODUCTION Most metal halides are soluble in water and dilute hydrochloric acid. The exceptions are silver ion, Ag mercurous ion, Hg,: and lead(II) ion, Pb. Consequently, the addition of HCI to a solution of metal cations leads to the selective precipitation of these three ions. While the theory behind the separation and identification of these ions has been outlined in the general discus- sion of the qualitative analysis scheme, some aspects of this chemistry need to...
