Hydroxides?
Hello,
I have a question about the reaction of metals with water.
This produces up to 3+ (partially 4) hydroxides. (Alkali metals, alkaline earth metals…)
Now to my question: Alkaline earth metals do form hydroxides, but they're very poorly soluble solids, right? While alkali metals, such as sodium, form highly soluble solids, right? I'm just concerned with solubility.

alkaline earth metal hydroxides are relatively poorly soluble in water, yes. The alkali metal hydroxides are rather water-soluble. NaOH and KOH even very good, but LiOH is pretty bad. So a flat-rate statement about everyone is not really in.
Okay, can they be called fumigs? But one can certainly say that compared to alkaline earth metals, these dissolve better.
They’re all solid. And how good they dissolve is in principle the same as solubility. And this is not the same for all hydroxides of the alkali metals or alkaline earth metals.
Okay.
