Introduction

Testing liquids for polarity-Chemistry lab Abhay P. XI D Aim: To determine whether the following liquids are polar or non-polar in nature Apparatus: - Cyclohexane, Distilled water, Carbon tetrachloride, Ammonia solution, Cyclohexene, Benzene, Acetone, beaker, burette, funnel. ...read more.

Middle

This is because a deflection on stream of liquid from the burette by a charged polythene rod indicates that the liquid consists of polar molecules. A polar molecule has a slight positive or negative charge and so when it is brought near to a charged rod it undergoes deflection. ...read more.

Conclusion

* Any two compounds should not be kept close to one another as the vapours from one compound may affect the polarity of the other. * We should keep rubbing the polythene rod either to your hair or on a woollen cloth to make sure that it is charged. * We should clean the apparatus properly to remove any other impurities. ...read more.
