Gypsum Identification
« on: August 22, 2012, 04:38:37 PM »
Hi

Is there a fast way to check if the salt deposits I can see in my experiment are dihydrated Calcium Sulfate?

Much appreciated

There are chemical reactions specific to calcium and sulfate, yes.  You might also be able to identify the crystals by their physical properties.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

As a first approximation try an elemental analysis. Do you at least have Ca / S in them? :)
