Phase Equilibrium

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 10 – Final)

16 June 2011

Chromatography is techniques used in laboratories for the separation or analysis of complex mixture. While it is easy to understand what chromatography does but not many knows the process in simple terms. So how does chromatography works? Berry Berry Easy would say that it is simply a process (will use a generic example) where: when [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 9)

13 June 2011

Continuing from Part 3,5 and 6 of Berry Berry Easy‘s short notes on Phase Equilibrium for STPM Chemistry Form 6 students, this Part 9 in the series will also be focused on ideal solutions and non-ideal solutions and miscibility. To remind students who missed out on the previous parts, ideal solution and non-ideal solution differs in [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 8 )

8 June 2011

The partition law, or also commonly known as the distribution law in chemistry (not to be confused with legal terms) refers to the principle where proportionate distribution of a solute occurs when it is added to a two-phase system (at a given temperature). The proportion is based on the solubility level of the solute in [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 7)

3 June 2011

This post, Part 7 of Berry Berry Easy short study notes for STPM Chemistry Form 6 on Phase Equilibrium will be focused on a mish-mash of solution properties such as boiling point and freezing point. Also discussed are ways to alter their values and the underlying principle behind the ability to change it. The colligative [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 6)

1 June 2011

Immiscible liquid or even miscibility will be terms which are new to most Berry Readers. However, if we were to use layman’s terms, miscibility will simply mean the ability of molecules to dissolve in other molecules. However, we’re learning chemistry, so we ought to use more accurate terms. Hence, it’ll be better to use the [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 5)

30 May 2011

The differences between ideal solution and non-ideal solution are something that students usually find it easy to memorise but hard to really understand. Most students tend to focus on the obvious differences like the intermolecular forces of attraction, volume change and enthalpy change. It is more important to say that ideal solutions are solutions which [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 4)

11 May 2011

Distillation process is simply a process of separating mixtures (such as crude petroleum or other mixtures) based on the variation in the volatilities of the components in the mixtures, usually done in high temperature conditions. This Part 4 of Berry Berry Easy‘s short notes on Phase Equilibrium for STPM Form 6 Chemistry attempts to explain [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 3)

5 May 2011

Raoult’s Law is one of the more difficult concepts in STPM Chemistry’s Phase Equilibrium. This is due to the different ways of stating the Raoult’s Law appearing in the various texts that students might encounter. The discrepancies in the ways to state Raoult’s Law stems from the different situation used when expressing the law. Worry [...]

Boiling point or more frequently abbreviated to B.P. or bp, is simply the temperature of an element or substance at which liquid boils. The boiling point is dependent on the relationship between the vapour pressure and temperature of the surroundings. While all might seem unrelated to Berry Readers at the moment, but this Part 2 [...]

STPM Chemistry Form 6 Notes – Phase Equilibrium (Part 1)

30 April 2011

Phase equilibrium are relationships of equilibra between the various phases of a chemical compound or mixture when taken under different conditions of composition, temperature and pressure. The phases can be vapour, liquid, solid or others. This Part 1 notes for Berry Berry Easy‘s short notes on STPM Chemistry Form 6 Notes – Phase Equilibrium focuses [...]
