Do the standard states still hold when it operates?

    Standard States
AI Thread Summary
A voltaic cell typically operates with reactants and products that are not in their standard states, as the concentrations of substances change during operation. While it is true that some rare cases may involve standard states, the general principle is that voltaic cells function with varying concentrations, which is essential for their operation.

A voltaic cell is composed with reactants and products in their standard states.So when it operates,the concentration of all substance must change,it should no be hold.Am i right?

While this statement can be right for some rare cases, in general most cells are not made with reactants in their standard state, quite the opposite. (Which actually answers your question, just not directly).
 

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 '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!!
