Question

Can one take oxalic acid solution in the burette and sodium hydroxide solution in the
titration (conical) flask ? Point out the limitations of doing so if any.​

Answer 1

Answer:

The known volume is usually taken using a pipette which can measure only one fixed volume, like 10 mL or 20 mL. The other solution is taken in the burette and added in small quantities into the pipetted solution. ... The person doing the titration should take care not to spill or splash solutions

Explanation:

Answer 2

$\boxed{\huge{\sf{NO}}}$

It is not recommended to take oxalic acid solution in the burette and sodium hydroxide solution in the titration flask because of the following limitation:

• When sodium hydroxide solution is allowed to titrate with oxalic acid solution we need to use phenolphthalein as an indicator.

• So, initially the reaction mixture is acidic and as a result the colour of the solution will be colourless

• So, after reaching the endpoint of titration there will be colour change from colourless to pink in the reaction mixture.

• The accuracy of noting this colour change (from colourless to pink) is much less then the accuracy of noting colour change from pink to colourless.

• Hence , it is recommended to take oxalic acid in the titration flask and sodium hydroxide in the burette.

This limitation can be well explained while performing titration during lab practicals in schools.
