Aluminum + Hydrochloric Acid: Making Aluminum Chloride

AI Thread Summary
Using aluminum with hydrochloric acid can yield aluminum chloride hexahydrate. To achieve this, it is necessary to convert hydrochloric acid into hydrogen chloride first, potentially using concentrated sulfuric acid. The dissolution of aluminum in acids is generally slow due to the presence of a resistant aluminum oxide layer, which complicates the process. For those aiming to produce hydrated aluminum chloride, scraping the aluminum surface may help to some extent, but its effectiveness is uncertain as the oxide layer forms quickly.

Hydrochloric acid and aluminum will give aluminum chloride hexahydrate. To make aluminum chloride you need to turn hydrochloric acid into hydrogen chloride first. Concentrated sulfuric acid might be helpful.
 
It is not clear what you want - if the anhydrous chloride, DrStupid remarks are spot on. If hydrate is OK, that makes things easier, but still difficult, as the dissolution of aluminum in acids is very slow, aluminum oxide is quite resistant (it dissolves much easier in alkalis).

yes, I want to produce hydrated aluminum chloride, and just by slice of wastage aluminum and HCl(37%)
can I scrape aluminum surface to speed up the reaction?

You can try, but I am not convinced it will work, oxide is created quite fast.
 

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!!
