actual acids are pretty much all clear i think
and specifically from the greenish hue of chlorine gas and the green glow of radioluminescent materials like radium on watch dials

Water's not blue either. It's that way because how else are you supposed to convey what it is to the player? If it's clear they'll just think it's water.
i believe the concepts of 'acid' and 'radioactive waste' got combined in a lot of designer's minds into the single concept of 'toxic waste' which is green and glows and corrosive. i've also seen some games try to make 'acid' yellow, but i can't answer your inevitable follow-up "why would acid be yellow" with any actual answer beyond "feels right"
(edit oh, you answered this same thing in a followup post :) )
