Question

What precautions should be taken while changing the liquid of Ostwald Viscometer?​

Answer 1

Answer:

1) The viscometer should be held in a vertical position during the flow of the

liquids.

2) While sucking the liquids, no air bubble should be formed inside the

capillary tube.

3) The volume of the liquids taken in bulb C should be so much that when

sucked up to mark X, it should fill the bulb A and a little should still remain

in the bulb C.
