Homework Help: hirsch funnel filter paper

Posted by Cecilia on Tuesday, October 10, 2006 at 1:28am.

I used a filter paper that was too large for the Hirsch funnel and had to
fold it up around the edges. Why is it bad to fold the edges of the paper?

One reason is that it is difficult to "seal" the paper for a proper vacuum to be pulled. Another is that solid may creep onto the the other side (the underneath side) of the paper.
