Science Crime Busters B

The Science Crime Busters Wiki has fairly reliable information, though it is a wiki, so it cannot be trusted 100%. however, since it's made by science olympians, the wiki is usually one of the best sources, and almost always reliable.

The 2010 rules for Science Crime Busters don't say anything about this, and though my "gut feeling" tells me otherwise, I still have to ask: Are we allowed to test the liquids with any reagents event supervisors provide such as dH2O, HCl, and Iodine? So far I have only wafted the liquids and not mixed them with anything...though i do realize that i can't just mix the liquids in their given containers....so could we pour a little bit of the substance into a reaction plate then mix them?

Yes, you can use the given reagents to test the liquids. In some cases, you will even be given a dropper to help you get them into the wells of the reaction plate (or they'll just be given to you in a large pipette to begin with).

You have to be able to test with the regents. How else would you be able to tell H2O and H2O2 apart.

Thanks!

Does anybody have a chart that has mixture results? Me an my partner did it, but it didn't save. Thanks

If you shake them, the H2O2 will make bubbles, water doesnt

what is a good strategy for identifying mixed powders? does anyone know what kind of mixtures are most common for SCB? thanks!!

[haven chuck]

I've found that they usually like to give two very different powders, namely one that bubbles in HCl with one that doesn't. Try identifying those mixtures, along with ones like Flour and Baking soda (since it looks like cornstarch, and iodine will still turn black because of the Flour).
