it's unlikely.
both sulfuric acid and formaldehyde have strong smells, and *you* could definitely smell them. actually, their vapors are dangerous and in a lab they'd always be handled in a fume hood.
a dog could definitely smell them, possibly even if the bottle was closed. sulfuric acid has illegal uses and drugs are commonly formed as sulfates, but i'm not sure what the chemistry behind drug dogs is.
it seems unlikely that at least an ordinary drug dog would be trained to smell sulfuric acid, and at any rate it is not illegal for you to have a test kit. be aware of what rights you may still have, and *do not* carry anything illegal at the same time as a test kit. test kits aren't expressly illegal, and you wouldn't want to be caught with something that was because of one.
