Chromic Acid
Not normally used by DIYers, but occasionally used for extreme ceramic sink cleaning. Its exceptionally effective, but very toxic and should be avoided entirely.
- Can set fire to organic materials like paper and skin.
- Disposal creates serious problems, contaminating land and food crops.

Concentrated/Dilute
Much of the page is about the concentrated forms. Excepting of course hydroflouric acid, most of these acids are relatively harmless when diluted with water to about 5%. I think that needs to be more conspicuously expressed in the text (which I cannot at present edit).

- I don't recall the situation - doubtless a mis-understanding.
- Remark : I find (or mis-understand) "Note: This page has been protected so that only registered users can edit it." to be a little deceptive. The actual meaning, I suppose, is that only logged-in users can edit. Being registered is an insufficient prerequisite. John Stockton (talk) 20:02, 20 October 2015 (BST)
Hydrogen Chloride is a very nasty gas at all d-i-y temperatures; concentrated hycrochloric acid is an aquesous solution containing about 35% HCl.
Hydrofluoric acid will also be found as a solution, as the boiling point of pure HF is 19.5°C.
The final link under Citric Acid, MSDS, is dead.
I think that it would be useful to start each section with a link to the corrresponding wikipedia page(s).

The comments under risks for citric acid would I think apply to all acids on here
