We have a project in chemistry. We need to do experiments. Can you guys give me a problem/experiment we could do? Something like what is better this or this... Ex:what is better a phosphate or a phosphate-free experiment. I would appreciate it if you could give me the ingredients and procedure. We can't use the detergent since our teacher rejected it. Thanks!

Look at the question at the URL below. They're asking about sodium acetate handwarmers and why they need a little "clicker disk" to get them started.
One poster suggests seeing if hitting this stuff with a hammer might have a similar effect. You could take one apart and try it without the disk inside.
These things are cheap and the chemistry is pretty interesting. It might be a really neat project.

You didn't indicate the point of the experiment. One phosphate experiment that gives a good/bad result is :
Obtain some natural water. From a stream or lake or a pond. add phosphate fertilizer to it. You should see a heavy algae bloom. If you can, check the oxygen content before you add the fertilizer.

A very simple expt. with some basic chemistry: Pl. do the expt with fire safety precautions.
Over a cotton ball sprinkle some potassium permanganate. When some glycerine is added over the potassium permangate crytsals the coton ball will catch fire.
KMnO4 oxidizes glycerine and large amt. of heat is evolved which causes ingnition of the cotton ball. Also check if the ball needs to be soaked in a fuel to ignite, since I have never done the expt. myself but just read about it elswhere.

Determine the melting point of water.
Give the class a bunch of items, like thermometers, beakers, ice, water, salt, bunsen burners, hot plates, stopwatch, graph paper, etc.
Don't give a procedure. see if anyone can determine the freezing point of water.
This is massively educational. Sounds so simple. Has so many problems.

With an American penny, lightly scratch one edge and then scratch the opposite side. You should see silver. The 'silver' is actually zinc. Put this in HCl (muriatic acid, available @ any hardware store). HCl reacts with the zinc and not the copper. Overnight, the acid will dissolve the zinc and you are left with a tissue paper thin, hallow penny. Its kinda cool.
Best Answer??

assuming this is for a class and you'll have proper equipment and supervision i'd go with something you're interested in. i investigated the disolution of varios antihistamines in acidic and aqueous environments for my senior project.
