How Do You Use a Bulb-pipettes Instead of Graduated Cylinders Or Volumetric Flasks?

How do you use a bulb-pipettes instead of graduated cylinders or volumetric flasks?

You just use a pipet bulb to draw the liquid into the pipet to fill it above the line. With your finger on the top, you let the liquid out slowly until the miniscus is right at the line. Then pipet then contains exactly the volume indicated. Then, let the liquid flow out of the pipet. You should touch the tip of the pipet to the side of the beaker or flask that you are dispensing into. You should not blow out the last bit of liquid in the tip.

A few pieces of broken porcelain are added during distillation in a flask. Why?

yes, you can add 'broken porcelain' to a flask to prevent bumping during reflux or distillation.But modern boiling chips are generally manufactured for that purpose from one of several other materials (carbon, glass, alumina, etc), and will more reliably have a large number of nucleation points than broken porcelain, even assuming that you'd have such a thing in a modern lab.A few pieces of broken porcelain are added during distillation in a flask. Why?.

Is it wrong for a 12 year old to use a flask?

Hip flasks are pretty strongly associated with alcohol, specifically whiskey. If you are worried about what your parents and teachers will think, it would probably be safer to drink out of something else. You could get an insulated thermos with a screw-on lid, maybe? Something that seals and you can stick in your backpack without it spilling everywhere, but does not look super suspicious? Plus I bet something like that would keep your tea and coffee hot for longer - I do not think hip flasks are very well insulated. Good luck!.
