I’m looking for a definition of “solvent” in the context of " their ideas…constituted an effective solvent to the values and institution of the old society"
I look forward to your feedback.
adjective
1.

2.
(of a substance, esp a liquid) capable of dissolving another substance
noun
3.
a liquid capable of dissolving another substance
water is a solvent for salt
4.
the component of a solution that does not change its state in forming the solution or the component that is present in excess
Compare solute
5.
something that solves
European Intellectual History from Rousseau to Nietzsche
I would think it means that the ideas were destructive of the old values/institutions - they weakened, dissolved, eroded them. But a fuller context might suggest a different reading.
On first read it seems clear to me that “solvent” is a noun meaning that thing which dissolves another thing. I can’t see how it could possibly be an adjective in that context, since it’s unclear what that adjective would be modifying.
The 3 words you’re looking for are solvent, solute, and solution. The solute is the minor ingredient in a solution, the solvent is the major ingredient, and the solution is what you wind up with. So salt=solute, water=solvent, brine=solution.
I don’t see any chemical meaning for “solve” in this sense. The Oxford English Dictionary simply defines solve (noun) as “solution”, with a quote from Shakespeare, and strongly suggests it is a variant of “soil” meaning “the solution of a problem”.
The difference might be that solve/soil is old-fashioned or obsolete: Wiktionary says “now rare, chiefly law enforcement”, with quotes like “Good solve, Detective,” “Nice solve, Nancy Drew.” Similarly, “fail” for “failure” is marked obsolete or slang except for the phrase “without fail”.
