Its depth has been increased by the action of the chromic acid.
A saturated solution of chromic acid is also used for the same purposes.
For hardening the blastoderm I have employed, as usual, chromic acid, and also gold chloride.
Analysis of samples showed an average of 34% of chromic oxide.
Because a sixth of it is chromic acid, while other gems, as the garnet, are coloured by oxide of iron.
A salt in which the hydrogen of (hypothetical) chromic acid, HCrO4, is replaced by a metal or other basic radical.
chromic acid converts it into phosgene (carbonyl chloride, COCl2).
It precipitates with tannic and phosphotungstic acids but not with picric, acetic, trichloracetic, or chromic acids.
chromic salts are of a blue or violet colour, and apparently the chloride and bromide exist in a green and violet form.
Those are chromic acid, cuprous chloride (sub- or proto-chloride of copper), and bleaching- powder.
