    Standard State
AI Thread Summary
The discussion revolves around the application of Faraday's law of electrolysis, specifically the formula m = (Q/F)(M/z), where the user seeks clarification on the variable Q, which represents total electric charge. The user intends to conduct experiments involving nickel electrodes at varying temperatures and pressures and is looking for a way to incorporate these variables into the Q part of the equation. There is a request for a rewritten equation that visually represents this, along with a note that the original document referenced is lengthy and not user-friendly for quick reference. The conversation emphasizes the need for a clear formula that integrates temperature and pressure into the calculation of electric charge.

Here's my problem: I know this formula http://carlschroedl.com/chem/ib_extended_essay.pdf (pg 18) is an extended form of Faraday's law of electrolysis which is m= (Q/F)(M/z) where m is the mass liberated in grams, Q is the total electric charge passing through, F is Faraday's constant, M is molar mass of the subtance, z is the valency of the ions. The part of the long equation I don't know is the Q part of Faraday's law. I plan to do experiements at various temperatures and pressures, so I need a formula for the Q part of the equation that has pressure and temperature variables. If it helps I plan to use nickel electrodes with 5 cm x 1 cm dimensions at room temperature. Please help. I'm so utterly confused. Can the rewritten equation be an image please? You don't need to explain the indivual parts of that Q part; I understand that; I just don't know how to add a temperature and pressure variable to it.

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'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...
