Heterogeneous Ionic Equilibrium

STPM Chemistry Form 6 Notes – Heterogeneous Ionic Equilibrium (Part 6 – Final)

26 April 2011

Common Ion Effect refers to a the effect when two substances which will give the same ion when ionised are involved in a chemical equilibrium. There will be an effect in the degree of solubility in solution when it happens. Part 6 of Berry Berry Easy’s notes on Heterogeneous Ionic Equilibrium is exactly about the [...]

Solubility experiments or experiments involving saturated solution are important, as they allow the empirical value of molar solubility of a salt to be determined. This post from Berry Berry Easy, Part 5 on Heterogeneous Ionic Equilibrium for STPM Chemistry will be on the basics of solubility experiments, their methods and some pointers on predicting precipitation. [...]

STPM Chemistry Form 6 Notes – Heterogeneous Ionic Equilibrium (Part 4)

21 April 2011

Heterogeneous equilibrium situation occur when chemical equilibria and chemical reactions involving more than one phase occurs. A good example would be when an ionic compound partially dissolves in water such as calcium carbonate dissolving in water in a process called dissociation. In this Part 4 of Berry Berry Easy notes on Heterogeneous Ionic Equilibrium for [...]

Solubility products (Ksp) are equilibrium constants for saturated solution and solid formation. where precipitations are formed. It is an equilibrium constant for solution which contains sparingly soluble salt. It is linked to molar solubility, as the solubility product of salts are indication (indirect) of their solubilities expressed in mol/L, which is called molar solubility. When [...]

Solubility of ionic solids in water is determined by two forces governing the interaction between polar water molecules and ions, which forms crystals. The two forces are (1) Force of attraction between water and solid ions and (2) force of attraction between the oppositely charged ions. It is however not practical to know the exact [...]
