Titration Skills

Why is indicator added to a titration?

• To test for acids

• to show the endpoint

• to prove a reaction has happened

• to show a colour

When should you stop a titration?

• When you have added equal volumes

• When the indicator changes colour

• When you run out of solution

• When the solution is no longer acidic

What is the reading on this burette?

• 24.00cm³

• 25.80cm³

• 24.20cm³

• 23.90cm³

What is the correct sequence to clean a burette?

• deionised water, tap water, solution to be filled

• tap water, deionised water, solution to be filled

• solution to be filled, deionised water, tap water

• solution to be filled, tap water, deionised water

What is the correct sequence to clean a conical flask?

• deionised water, tap water, solution to be filled

• tap water, deionised water, solution to be filled

• tap water, deionised water

• deionised water, tap water

Hot to remove air bubble in the burette?

• no need to remove air bubbles

• shake the burette vigorously until the air bubble disappear

• tap the burette gently until the air bubble disappear

• open the tap to flush out the air bubbles

When filling up the pipette, where should you position the pipette?

• On the surface of the solution.

• Submerge in the solution.

During titration, when there are droplets of solution on the walls of the conical flask, you should .................

• ignore as it won't affect the results

• rinse the wall of the conical flask with solution in the burette

• rinse the wall of the conical flask with deionised water

• rinse the wall of the conical flask with tap water

During titration, you should swirl the conical flask constantly.

• TRUE

• FALSE

Which of the headings should be included in the titration result table?

• final volume, initial volume, volume of solution

• final reading, initial reading, reading of solution

• final reading, initial reading, volume of solution

• final volume, initial volume, reading of solution
