Investigating Color in Chemistry Lab: My Experience

AI Thread Summary
In a chemistry lab, a color test was expected to yield a blue result, but the observer saw no color. Teachers insisted the color was a faint blue, which was not indicated in the lab manual. The discussion raised the possibility of using a colorimeter to measure wavelengths and confirm the color. There are devices available that can measure wavelengths, but specific recommendations were not provided. The inquiry highlights the need for clarity in lab manuals regarding expected results and the tools available for accurate measurement.

in my chemistry lab we had a kind of color test.
the thing was supposed to come as blue according to the lab manual. . It did not. to me there was no color.however my teachers forced me to believe what i was looking at was blue,supposedly "it is very faint". that was not mentioned in the manual.

but colors are wavelengths right.
so can we use a colorimeter or anything to get some kind of data in wavelenght suggesting this can not be blue.

is there any other way? i don't really know what the compound we r looking at.

Maby you would be better off putting this in the chemistry section. There are devices that will measure wavelength for you, but I don't know what to suggest.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
