Introduction To Chemistry Flashcards
Properties of a metal
high MP/BP
Electrical conductors
Malleable
Shiny
Properties of a non - metal
low MP/BP
Not electrical conductors
Brittle
Dull
Element
A substance that only contains one type of atom
Compound
Two or more atoms chemically combined together
Mixture
Two or more atoms not chemically combined
Solute
The substance which is going to be dissolved
Solvent
The liquid which is doing the dissolving
Solution
The resulting mixture
Saturated
A solution which no more solute can be dissolved
Suspension
A solid floating in a liquid because it cannot dissolve
Soluble
A substance which can be dissolved
Insoluble
A substance which cannot be dissolved
Gas to Solid
Sublimation
Solid to Gas
Deposition
Gas to Liquid
Condensation
Liquid to Gas
Evaporation
Solid to Liquid
Melting
Liquid to Solid
Freezing
Simple Distillation is used for…
Seperating a solvent from a solution
(Seperating a liquid and a soluble solid)
Simple Distillation
- Solution is heated to vapour
- Vapour passes trhough a condenser –> pure liquid
- Solid is left behind
Filtration is used to…
Seperate an undissolved solid from a mixture
Filtration
- Place filter paper in filter tunnel
- Filter paper only allows small liquid particles to pass
- Solid particles collect in filter paper
Crystallisation is used to…
Chemical process
Used to form solid crystals from a solution
