AI Thread Summary
The discussion centers on the equilibrium between chromate and dichromate ions in relation to acidity. It highlights that in aqueous solutions, an equilibrium exists between these two anions, influenced by the pH level. The conversation also touches on the use of chromate and dichromate in the oxidation of alcohol, with the assertion that this process does not establish an equilibrium, as the original chromium species are fully reduced during the reaction. The main focus is on understanding the conditions under which the chromate-dichromate equilibrium can be observed, emphasizing the role of acidity as an independent variable.

I am trying to get an idea of an experiment that deal with the equilibrium of Chromate and Dichromate with acidity being the independent, but I am not sure in what situation would a equilibrium between these two chemicals occur.

Beside the interchange of these two anions with each other, I was also told that chromate or dichromate was used in the oxidation of alcohol, however, I do not believe using either would generate an equilibrium, and instead, the chromate or dichromate in the alcohol will all reduce into something else until none of the original chromium anion is left.

In water solutions there is always an equilibrium between chromate and dichromate, period.
 

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!!
