AI Thread Summary
Changing the type of reducing agent in gold assay tests, specifically from flour to argol, can significantly impact the fusion process and final gold analysis. Small modifications in analytical procedures can lead to unexpected results, making it essential to conduct preliminary tests on known samples to determine the comparability of results from both methods. This approach ensures that any variations in the assay outcomes are understood and accounted for, highlighting the importance of careful consideration in assay technique selection.

I am in need of help answering a question. I am an environmental geologist faced with the need to comment on techniques for gold assaying. Such questions are best left to mineralogists. My question: can changing the type of reducing agent in a gold assay test from flour to argol make a difference in the resulting fusion and final analysis for gold?

Disclaimer: I know nothing about assaying gold in particular. What I do know, is that small changes to any analytical recipe can have unexpected side effects, so you would need at least some preliminary tests done on a known samples to check if the results from both methods are comparable.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
