Question

What is the difference between prussian blue and Turnbull's blue??

Answer 1

Answer:

In former times, the addition of iron(II) salts to a solution of ferricyanide was thought to afford a material different from Prussian blue. The product was traditionally named Turnbull's blue (TB). X-ray diffraction and electron diffraction methods have shown, though, that the structures of PB and TB are identical.

Answer 2

The difference between Prussian blue and turnbull's blue are defined by some reason In former times, the addition of iron salts to a solution of ferricyanide was thought to afford a material different from Prussian blue.

The product was traditionally named Turnbull's blue (TB). X-ray diffraction and electron diffraction methods have shown, though, that the structures of Prussian blue and Turnbull's blue are identical.

•Turnbull's blue, formed by the reaction of ferricyanides and ferrous salts, has the same chemical composition as the iron blues ( MFe2[CN]6, in which M represents an ion such as sodium or potassium).

•Prussian blue is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts.
