How do I classify acids and bases in chemistry?

AI Thread Summary
To determine whether a compound is a strong acid, weak acid, strong base, weak base, or amphoteric, one should compare the original compound with its deprotonated form, focusing on stabilizing effects such as resonance. For organic molecules, conjugation may influence acidity or basicity. Strong bases are typically soluble strong electrolytes, often represented by salts of hydroxide ions, like NaOH, which dissociate in solution to release hydroxide ions that act as the base. The stability of the conjugate base or acid is crucial; the more stable the conjugate, the stronger the corresponding acid or base.

Can anyone explain to me how to determine whether a compound is a strong acid, weak acid, strong base, weak base, or amphoteric? Thanks!

For acids, compare the original compound with the deprotonated compound. Look for stabilizing effects like resonance. For select families of organic molecules, conjugation may play a part.

The only stong bases I know of are readily soluble strong electrolytes which are salts of hydroxide ions.
 
What is this? :

Your other descriptive information is good, but what is a salt of hydroxide ion? A base is not a salt.
 
For example, NaOH is a salt of a hydroxide ion. It goes into solution, dissolves into ions, and the hydroxide acts as the base.
 
Look at the stability of the conjugate. The more stable the conjugate, the stronger the acid or base.

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!!
