Can't Judge a Powder B

[ug]

new to the focrum
do you know if the kids has to do benedicts test

[robotman]

The rules only allow students to bring certain items Becuase of this and the line "the team may bring no other items" students may not bring the Benidicts testing solution.

However it may be a good idea to know how to do it as a proctor may present them with the materials needed for the Benidicts Test and than ask questions about it.

So even though they may not bring the Testing solution it is not a bad thing to know just in case

How do you tell the difference between an organic and inorganic compound?

[2win]

well... an organic compound is usually made of carbon.. but idk how you could figure out..

and does anyone know of a good place to buy a good conductivity tester? we have one, but it's not too good..

how to measure density of a powder which is soluble in water. We were using granulated cyclinder to see how much volume, but it gives only bulk density. Is that enough

How do you tell the difference between an organic and inorganic compound?

As far as I know, an organic compound will dissolve in rubbing alcohol and an inorganic one wont.

I think that's more a rule of thumb than an absolute.

I'd also like an idea of what kind of conductivity tester is normally used in this competition. This will be our first year trying out this event, and I'd hate to have the team disqualified for taking a "too-cool" tester.

Links of where to buy?
Any info appreciated.

Does anyone know what units to use exactly for a voltometer I was just taking a practice test and was confused on the units if you could help me with that it would be appreciated!

[CJAP Crazy MMM]

Acually not at all you make observations: Ph levels, Electrical conductivity etc..

so for this event, you have to be able to name powders? is that all?
