Question

the reason behind pouring the solution on the filter paper with the help of glass rod is
1) to increase the rate of filtration 2) to prevent taring of filter paper 3) to stick the charcoal to the glass rod
4) different than these

Answer 1

ANSWER :
_________

1 ). To increase the rate of filtration.

Answer 2

Filtration is the process of separating solid from a liquid.

We use a filter paper in this case.

Given that filtration involves the pouring of liquid onto a filter paper it is important to prevent the liquid from spillage as much as we can.

This is to ensure we do not remain with solid particles only during the separation.

To do this we can either use a filter paper or a glass rod.

Glass rod helps to direct the liquid into the filter paper.

This will ensure minimal spillage and hence will increase the rate of filtration.

The correct answer is thus :

To increase the rate of filtration.
