Low-pH substance (4)

Ross

I believe the answer is:

acid

'low-ph substance' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for acid that I've seen before include "Tart, sour" , "Drug LSD (colloq.)" , "It is neutralised by alkali" , "scathing" , "It is neutralized by alkali" .)

I've seen this clue in the Universal, the LA Times and the USA Today.
