Question

Which is the correct reading to be considered while carrying out titration? State the reason for your answer.​

Answer 1

Answer:

Explanation:

1)Usually an air bubble is present in the nozzle of the burette,it must be removed before taking the initial reading.

2)Their should not be any leakage from the burette during titration.

3)Keep your eye in level with the liquid surface while taking the burette reading or while reading the pipette or measuring flask etc.

4)Always read lower meniscus in case of colourless solution and upper meniscus in case of coloured solutions.

5)Do not blow through the pipette tp expel the last drop of solution from it,simply touch the inner surface of the titration flask with the nozzle of the pipette for this purpose.

6)shaking of the titration flask should be continous during adding the solution from the burette.

7)Use your index finger while pipetting the solution
