ferric salt

It has to be absorbed in another form such as a ferric salt.

A famous reaction involves treatment with ferric salts to give Prussian blue.

Ferric salt as the "solution link" in the stability of ferric oxide hydrosol.

It reacts with ferric salts to form a deep-red ferric thiocyanate complex:

Aluminium salt lakes are usually coloured blue-white, whereas ferric salt lakes are coloured blue-black.

Commercially available, this compound may be prepared by oxidizing ferrocene typically with ferric salts followed by addition of fluoroboric acid.

Although aniline is weakly basic, it precipitates zinc, aluminium, and ferric salts, and, on warming, expels ammonia from its salts.

Because gallium(III) and ferric salts behave similarly in biological systems, gallium ions often mimic iron ions in medical applications.

They also recommend to avoid the inclusion of iron and ferric salts, heavy metals, formaldehyde donors and PABA and PABA esters.

To make a Pellet print, a paper (or more rarely drafting linen) support is coated with ferric salts suspended in a gelatin emulsion, placed under a translucent original drawing, weighted with glass, and exposed to ultraviolet light.
