AI Thread Summary
The discussion revolves around the properties and concentration of a 1M sulfuric acid solution found in a small bottle. Initial experiments suggested the solution might be weak or even water due to a lack of distinct smell and minimal corrosive effects. A participant tested the pH, finding it to be 1, which indicates a concentration similar to hydrochloric acid in the stomach, suggesting it is not highly concentrated. Despite the low pH, there were concerns about its corrosiveness, as one individual poured it on themselves without experiencing harm. The conversation highlights that a true 1M sulfuric acid solution should be irritating upon contact, raising questions about the actual concentration and safety of the substance. Further testing, such as titration, was suggested to determine the exact concentration if the pH were higher than expected.

Me and some friends recently stumbled upon a 1M solution of Sulfuric Acid. It's in a small 30 ml bottle and has no distinct smell. After running a few amateur experiments (pouring it on stuff), we concluded that it is either extremely weak or simply water. I know from ap chemistry a few years ago that a 1M solution would contain a mole of H2SO4 per liter, or something of the sort, but I am not sure how strong this is. Is there any tests that i could do to tell if this is simply water or if someone diluted the mixture even further? Or is it extremely obvious from the explanation that it is water?

If pH is much higher than about 1, it might be less than 1 M sulfuric acid - exact pH value I'm not sure. If pH is higher than about 2, you can titrate to find the exact concentration (you can titrate the acid no matter the pH, really.). In case the pH is over 6, it is far too dilute to be close to 1 M.
 
Have you reacted it with baking soda?
 
Yea I finally got some ph strips and found the ph to be 1 surprisingly. Why does it not corrode anything. Although i warned him not to, a crazy friend poured a large amount on himself and it did nothing.
 
pH 1 means it is about as concentrated as hydrochloric in your stomach. Not very high concentration of acid.

At 1 M the solution would be irritating after a couple of minutes.
 
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...
