Carbon Electrodes Electrolysis Neutral 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.

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 'Enthalpy - published values'

Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.

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!!
