Ask Mr. LG anything! (ALMOST). By Mr. Lang. Questions-705. How does distillation work? A- 2 processes- evaporation and condensation. Solvent and solute is retained.

A- 2 processes- evaporation and condensation. Solvent and solute is retained.
In paper chromatography, when you say that the colours separate on the filter based on the solubility of each different colour, what do you mean by “solubility”?
A- Paper chromatography- each colour has a different ATTRACTION to the solvent and the filter. The more attraction, the farther the colour will travel.
A- Based on its overall appearance, we would classify it as a pure substance.
What is the relationship between solubility and the particle theory?
A- solubility is a measure of how easy a solute dissolves in a certain solvent. If something dissolves easily, it means that the particles have a high attraction to each other.
A- In a solid the particles are packed tightly together unlike the particles of a liquid or gas. Solids have a stronger force of attraction so we cannot walk through them.
What if we mix 2 things together and they look the same? What do we do to separate them back?
A – we can use evaporation, distillation or in some cases, paper chromatography to separate solutions
A- Heat provides the particles with kinetic energy. Particles use the kinetic energy for movement. The more heat there is, the faster the particles will move.
