Thanks moltenmetal, I theorized that this was what was happening with the Cl-, but how does this explain this phenomenom when combined with dextrose and there is no chlorine present? What happens then? Kaos1

Greetings, In a recent situation in our process, we have noticed that when dispersing ferric nitrate nonahydrate, which is light purple or brownish depending on it's state, on sodium chloride it turns to a bright yellow. We have tried NaCl, KCl, dextrose, and calcium chloride as...

Greetings, I am reposting this question. Any takers? Solid-Solid Reactions References?

MortenA, Thanks for your input. All equipment is in calibration and standards were run before testing the samples. Another note: The powder is not comprised of a single entity but a blend of approx. 50 different chemicals. Kaos1

Greetings, Being new to this, I have submitted a sample of a powder that we produce for particle size analysis. Two methods were used: "Time of Flight" and Laser defraction. Each gave very different results. Time of Flight gave a nice standard bell curve and the Laser Defraction...

Greetings, Is there a handy reference book that can be used in determining solid particle to particle reactions? We mill fine powders and have seen some chemical to chemical reactions in our blending chamber. Because the particle size is small, any reactions that may occur are only increase...

Greetings, We manufacture fine powders for the biotech industry. These powders are comprised of salts, sugars, amino acids, vitamins... The stuff that is necessary for cells to live. The question has been raised, How fine is too fine? This is in reference to the powder (we mill it from raw...
