A while ago, I read that salicylic acid can make boric acid solution strongly acidic when it's added to it.
To my knowledge, I know that boric acid becomes a strong acid in presence of cis-diols (except ethylene glycol). I also know that it happens due to increased stability of conjugate base by chelation using polyhydroxy compounds.
But I can't really make out the case with salicylic acid. I will be really thankful if you could shed some light on this topic.
