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).

You should be able to edit so long as you are logged in... is this not the case? --John Rumm (talk) 18:47, 18 October 2015 (BST)

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)

Yes I see your point, its not the best message. Having said that, if you are not logged in, how would it know you are a registered user? ;-) --John Rumm (talk) 09:51, 23 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 NT (talk) 03:56, 22 October 2015 (BST)
