Are all acid have covalent structure in solid state?

AI Thread Summary
The discussion centers on the structural nature of acids in their solid state, specifically addressing whether all acids possess a covalent structure. It acknowledges that there are no substances that are purely covalent or purely ionic, highlighting that covalent bonds can exist, such as those between identical atoms like in O2. When acids are not dissolved in water, they are believed to have covalent bonds within the compound and exhibit intermolecular forces, including dipole-dipole interactions and hydrogen bonding, between molecules. This indicates a complex interplay of bonding types in solid acids.

You are aware of the fact that there are no things like "purely covalent" and "purely ionic"?
 
I think there are purely covalent bonds (like between identical atoms. Between oxygen atoms in O2?).

Anyway, when not dissolved in water, I think acids would have covalent bonds between atoms in the compound and intermolecular forces (dipole-dipole interaction, hydrogen bonding, etc.) between molecules.
 
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...
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!!
