Sodium bicarbonate does not readily react with copper hydroxide in water due to the insolubility of copper hydroxide (Cu(OH)2). The proposed reaction equation is Cu(OH)2 + 2NaHCO3 = CuCO3 + Na2CO3 + 2H2O. While this equation suggests a reaction could occur, the insolubility of both Cu(OH)2 and the resulting copper carbonate (CuCO3) would hinder the reaction's progress. The discussion highlights that the reaction's feasibility is influenced by factors such as concentration and sample preparation, indicating that a poorly defined question complicates the analysis of potential reactions.

does sodium bicarbonate react with copper hydroxide in water ?
what is the equation?
So if it is not soluble, how is it going to react?

A possible reaction might be:
Cu(OH)2+2NaHCO3=CuCO3+Na2CO3+2H2O
The fact that Cu(OH)2 is insoluble would slow down the reaction. But since CuCO3 is also insoluble, the insolubility of Cu(OH)2 would at least not force the reaction to the left.
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.
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!!
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...
