Question

Why remove funnel from burette before titration?

Answer 1

we are removing funnel from burette before titration because when we are passing chemical from funnel while filling burret with chemical there some droplets left in the funnel which slowly comes in the burret but as we know that we are taking chemical till mark " 0" and in titration even one drop can make a difference in our calculations because we are calculating it by having our initial point as "0"or any (if we are calculating in continuous experiments)

hence so to avoid mistake in your reading it is necessary to remove funnel before titration

Answer 2

It is a precaution to be taken care of and is done so that any drop of liquid present in the flask may not drop into the burette and affect the readings.
