Acid fertilizers

Is there a thread that classifies fertilizers into how acidic they are? I have an inkling this maybe a something I should work out myself but how do I know what fertilizer I want or check an acidic one over a basic one.

Can I just litmus test my bottle of fertilizer in the hope it's as easy as that, I doubt it but I don't know salts this well.
