Why are carbon electrodes neutral in electrolysis of water?

AI Thread Summary
The atomic structure of carbon electrodes contributes to their neutrality in electrolysis due to their stability and resistance to dissolution in ionic form, unlike most metals. While noble metals are resistant to dissolution, their high cost limits their use. Carbon can undergo oxidation to form carbon dioxide; however, this process is slow and results in a gaseous product that readily escapes the solution, minimizing its impact on the electrolysis process. This unique behavior makes carbon electrodes a practical choice for electrolysis applications.

What is it about the atomic makeup of carbon electrodes that makes them neutral in electrolysis?

Most metals easily dissolve in ionic form (unless they are noble metals - but these are expensive). Carbon can be oxidized to carbon dioxide, but this is a slow process, besides, product is a gas, which will easily leave the solution.
 
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...
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!!
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...
