[Histonet] Chromic Acid Disposal

[Tyrone Genade]

Hello,

For the disposal of Chromic acid see
https://www.chemistry.nus.edu.sg/PSSO/safety/Special%20Chemical%20Waste.htm
 and
https://study.com/academy/lesson/chromic-acid-solution-preparation-disposal-hazards.html
(more
detailed).

You can precipitate the chrome as Cr(III) and store this solid for waste
disposal instead of liquid chromic acid. In the process the acid is
neutralized and the supernatant (of sulfates, potassium and sodium ions)
diluted and washed down the sink.

I hope that helps.
