AI Thread Summary
The discussion centers on the quest for purer acetone, with the original poster expressing dissatisfaction with the 99.5 percent purity of their purchased acetone. They have attempted to improve purity by adding anhydrous magnesium sulfate, which they shake and let sit overnight, but seek confirmation on the effectiveness of this method and whether it is appropriate. There is also curiosity about the potential use of activated carbon for further purification. Additionally, concerns are raised about whether the magnesium sulfate might leach water back into the acetone over time, prompting a question about the necessity of filtering it off after a set period. The poster references a scientific source for further insights into the topic.

I bought a can of acetone recently. I called the manufacturer and they said that the acetone was 99.5 percent pure. This is not good enough for me. I need it as pure as possible. I have tried tossing in anhydrous magnesium sulphate (about 40 grams per litre), shaking well for a couple minutes, then letting it sit overnight. This seems to result in a more pure acetone, but i am a perfectionist (by the way, was there anything wrong with my drying procedure?)

I was wondering if using activated carbon would work better? I will of course try it out and see how it works, but i would like some direction in purifying my acetone even more.

Also, will the mag sulphate i used leech water back into the acetone after a while? Or should i filter it off after letting the can sit for, say 24 hours?

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

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...
