Another phosphoric acid question- Please respond if you have an answer!
We are running a machine to measure calcium carbonate by the pressure
evolved-no mass spec! :-(
(reacting samples under vaccum in a common acid bath at 80 deg C)
Although using the dry acid has been suggested, is there a reason we can't
just use off the shelf 85% ortho phosphoric acid, avoiding the hydrogen
peroxide, chromium trioxide altogether?
thanks,
dave anderson
