Experiment 10 Solubility product of calcium hydroxide by titration
(7th 11th Feb.)
Objectives: Write the objectives of the experiment (following the example given for Expt. 1)
Relevant constants:
Mr of calcium hydroxide
Results:

pH and Buffers
The definition of acids has evolved over time:
Arrhenius
Bronsted-Lowry
Lewis
Arrhenius definition:
Acids when dissolved in water increase the conc. of H+ ions e.g. HCl
Bases when dissolved in water increase the conc. of OH- ions e.g. NaOH
Solubility Equilibrium
Saturated solution one in which the solution is in contact with undissolved solute.
(i.e. there is excess solute present in the solution)
e.g. A saturated solution of BaSO4 has some solid BaSO4 present in the solution:
saturated BaS
Redox Reactions
Oxidation is loss of electrons.
Reduction is gain of electrons.
OILRIG
Change in oxidation numbers/ states can also be considered:
Oxidation oxidation number/ state increases
Reduction oxidation number/ state decreases

Strategy of Synthesis
How do we assess the quality of a synthesis?
Number of steps - lower the better (usually) - there are various methods for decreasing
the number of reaction step
Solvents and Nucleophilicity
In general chemistry, we classified solvents as being either polar or nonpolar. Polar solvents can
be further subdivided into protic and aprotic solvents.
Protic Solvents
A protic solvent is a solvent that has a hydrogen atom
