AI Thread Summary
Titanium dioxide is generally considered an inert material, but caution is advised when it comes to its interaction with strong acids and oxidizers, as indicated in its Material Safety Data Sheet (MSDS). The concern primarily arises from its potential role as a catalyst in reactions with these substances, rather than undergoing chemical alteration itself. While it remains nonreactive at room temperature, the behavior of titanium dioxide changes at elevated temperatures, where it can act as an oxygen donor. Understanding these properties is crucial for safe handling and application in various chemical processes.

I've thought of titanium dioxide as a very inert material--until yesterday when I was reading its MSDS and found out it shouldn't be combined with strong acids or oxidizers. Why? Is this at room temperature or several hundred °C?

Not combining it with reactive metals makes sense to me--it's an oxygen donor at elevated temperatures, but at room temperature it's nonreactive.

Oh, I think I might have my answer now: it's functioning as a catalyst in reactions involving oxidizers and/or acids; it's not chemically altered itself by them.
 

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...

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!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
