Do I Need a Battery for a Positive Redox Reaction?

AI Thread Summary
In reactions with a positive electric potential, such as one with E=1.34V, it is not necessary to connect electrode terminals to an external battery to provide that voltage. If the reaction can occur spontaneously, the electrodes will inherently possess the required potential. This indicates that spontaneous reactions can generate the necessary voltage without external assistance, emphasizing the self-sustaining nature of certain electrochemical processes.

For a reaction where the electric potential is positive, does there need to be something to provide voltage for the reaction to occur? Let's say E= 1.34V for the reaction. Do I need to connect the electrode terminals to a battery to provide 1.34V?

Nope. As long as the reaction can occur spontaneously, the electrode terminals will have a potential.
 

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!!
