Revision workbooks
If you haven't yet bought your revision workbooks you can still buy them through school for £4 and revision guides are £2.50. Well worth the investment!

Why not universal indicator?
You can't use universal indicator for titration because it doesn't give a single, sharp colour change. Simple as that. Nothing to do with time!

Why is it alkaline?
If the electrolysis of a solution (say, sodium chloride) produces a halogen gas (like chlorine), it doesn't produce oxygen. Therefore, hydroxide ions from the water remain in the solution. Lots of hydroxide ions means the solution is alkaline! See electrolysis notes below for more info.
Controlled Assessment
Great to see so many of you working hard after school today :) Come along again tomorrow for a shorter drop-in session from 2.30pm.
