AI Thread Summary
Lead iodide has the chemical formula PbI2 because lead typically exhibits a +2 oxidation state, which is the most stable form for this element. While lead can exist in multiple oxidation states, including +4, the +2 state is predominant in this compound. Iodine, on the other hand, requires only one electron to achieve a stable octet, leading to the formation of PbI2 rather than PbI4. This understanding clarifies the composition of lead iodide.

**EDIT** Never mind just realized that it is lead(II) in PbI2. Hehe... Awkward
Why does lead iodide have the formula PbI2?
Pb needs to lose (or gain) 4 electrons to have a stable octet and Iodine needs to gain only 1. So why isn't the equation PbI4? It seems like it should be... Please explain if you can.
Thanks :)

Lead is one of those elements with multiple oxidation states (either +2 or +4). The most common state is +2, which is why lead iodide is PbI2

Haha I just realized. Thanks :D
 

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...
