What is the colour of Fe 3?
Solutions that are yellow in colour usually contain Fe3+ ions.
What color is cocl4?
blue
Explanations (including important chemical equation): The Co(H2O)62+ complex is pink, and the CoCl42- complex is blue. This reaction is endothermic as written, so adding heat causes the equilibrium constant to shift to the right.
What colour is CuCl4 2?
When concentrated hydrochloric acid (HCl) is added, tetrachlorocuprate II complex ions ((CuCl4)2-) are formed. These ions are yellow in colour, which with the blue colour of copper ions results in a vivid green coloured solution (centre left).
What color is fecl3?
Ferric chloride is an orange to brown-black solid.
What colour is cr2o72?
The Orange colour of Cr2O72– ion changes to yellow when treated with an. alkali.
What colour is mno4?
Because the manganese atom is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media….Permanganate.

What colour are chromium ions?
In the presence of chloride ions (for example with chromium(III) chloride), the most commonly observed colour is green.
Why is CoCl4 blue?
while in CoCl4(2-),Co2+ ion surrounded tetehydrally by4 Cl- ions acting as ligands. The main electronic transition is L→M is charge transfer(Cl- →Co2+ )which is fully allowed ,responsible for intense blue colour.
What is cocl42?
[CoCl4]2- – Cobalt tetrachloride.
Why is zn2 ++ Colourless?
Copper has an unpared electron which acts as a F centre and allows electron transition in visible region importing color while Zn+2 is having no unpaired electrons hence colorless.
Why is Hexaaquacopper blue?
If you add an excess of ammonia solution to hexaaquacopper(II) ions in solution, the pale blue (cyan) colour is replaced by a dark inky blue as some of the water molecules in the complex ion are replaced by ammonia. The first complex must be absorbing red light in order to give the complementary colour cyan.
What is the colour of Fe OH 3?
Iron (III) hydroxide is a chemical compound made of Iron, hydrogen and oxygen with a chemical formula Fe(OH)3. Depending on the hydration, crystal structure and particle shape and size, the colour of iron III hydroxide varies from dark-brown to black.
