A Level Chemistry RP1 - Titrations
| Front | State and explain 2 ways to reduce percentage uncertainty in a burette without changing apparatus (4) |
| Back | - increased concentration of solution in conical flask. larger titre volume required from burette to react, so smaller error - decrease concentration of solution in burette. large titre volume required from burette to react, so smaller error |
| Front | Describe a standard solution |
| Back | solution of a known concentration |
| Front | Explain why a funnel must be removed from a burette |
| Back | - drops of substance may fall from funnel during titration into conical flask- titre volume smaller |
