AI Thread Summary
RFID wallets function primarily as a Faraday cage, blocking unauthorized radio waves rather than relying on chemical additives. The composition of materials, such as leather, can vary, with vegetable-tanned leather containing fewer chemicals than chrome-tanned leather. However, the residual chromium in chrome-tanned leather does not impact the wallet's ability to block radio waves. Typically, an RFID shield is integrated between the layers of the wallet's material to enhance protection against unauthorized card reading.

The way they work has nothing to do with chemistry, it is just a Faraday's cage blocking radio waves.

Lots of chemicals in leather, though. Veg tan leather has fewer than chrome tan leather. Most consumer leather wallets are chrome tan. The residual chromium has no effect on radio waves though.
A shield is glued between the various layers of leather or whatever material the wallet is made from.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
