Q
How to improve titration
A
- Swirl flask during titration to make sure alkali + acid react properly
- rough run, for a rough idea of the titre
- add acid drop by drop when within a few cm3 of a rough titre
- burette
- volumetric pipette

4
Q
if pressure is increased…
A
equilibrium position moves in the direction of the FEWEST moles of gas
5
Q
if concentration is increased…
A
equilibrium position moves in direction AWAY from side where con was increased
6
Q
if temp increased…
A
moves in direction of ENDOTHERMIC reaction as heat will be used up
