Explain how air bubbles in the buret tip migh6 lead to poor results. How should the air bubbles be removed?
Homework Answers
The air bubbles in the buret occupy some volume that has to be occupied by the liquid therefore observed liquid volume is less because small amount of volume is occupy bubble.
The problem can be eliminated by:
1) renise the test tube with inert solvent or the with solvent that is to be used in experiment before experiment is performed.
2)wash the buret with distilled water or normal water before used.

3. There is an air bubble in the tip of your buret, but you start the titration anyway. Some time during the course of the titration, the air bubble is dislodged and leaves the buret. Your final titration volume will be a) fine, the air bubble was not an issue b) too great, but the calculation should be ok c) too small, this titration is ruined d) too great, this titration is ruined
