- make a factsheet for every element (or gas) that you know
- take the first titre into account too!! 2 dp plese
- hno3 is not suitable for use as a primary standard because it is unstable
- suitable PS in acid-base titration -- ethanedioic acid (h2c2o4)/ na2co3
- the reaction between WA and WB give no sharp change in pH at equivalence point, so no indicator is suitable
- nh4+ +oh- -> nh3 + h2o (bc it's neutralization)
- but nh3 + hcl is just nh4+ (aq)don't ask
- naoh is unsuitable as a PS as it REACTS not absorbs co2
- i2 solid is dark brown, aqueous i2 is brown, i2 gas is purple
- trans isomers: higher mp; cis isomers: higher bp
- br 2 aq does not react w alcohols
