need to find out what Phil is doing (credentials)
Need to establish that we are A TEAM and that the Tutors are fantastic- so they don’t have problems when assessment arrives as a shock

2. Solutions Homogeneous mixtures of two or more pure substances.
The solvent is present in greatest abundance.
All other substances are solutes.

3. Displacement Reactions
In displacement reactions, ions oxidise an element.
The ions, then, are reduced.

4. Displacement Reactions
In this reaction, silver ions oxidise copper
metal:
Cu(s) + 2 Ag+(aq)  Cu2+(aq) Ag(s)

5. Displacement Reactions
The reverse reaction, however, does not
occur:
Cu2+ (aq) + 2 Ag (s)  Cu (s) + 2 Ag+ (aq)

7. volume of solution in litres
Molarity
Two solutions can contain the same compounds but be quite different because the proportions of those compounds are different.
Molarity is one way to measure the concentration of a solution.
