What is the oxidation state of cocl4 2?
+2
is a tetrahedral complex ion with coordination number of 4 as the models show. Oxidation state of cobalt is +2 and you should be able to determine the OS given the complex ion formula only.
What is the shape of cocl4 2?
The [CoCl4]2- complex ion is experimentally known to have a tetrahedral structure.
What is the hybridization of cocl4 2?
One 4s and three 4p orbitals participate in hybridization.
What is the oxidation number of wo3?
6
The oxidation number of tungsten in tungsten trioxide is 6.
What Colour is CoCl4 2?
blue
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 is the formula for WO3?
WO3Tungsten trioxide / Formula
What color is CoCl4?
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.
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 colour is CoCl4 2?
Is CoCl4 2 endothermic or exothermic?
endothermic
The reaction [Co(H2O)6]2+(aq) + 4Cl–(aq) → [CoCl4]2–(aq) + 6H2O(l) is endothermic. Therefore, in accordance with Le Chatelier’s principle, when the temperature is raised, the position of the equilibrium will move to the right, forming more of the blue complex ion at the expense of the pink species.
How do you determine the oxidation state of a carbon atom?
The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each bond to more electropositive atom (H, Na, Ca, B) and +1 for each bond to more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. For example:
What is the oxidation state of Co in ethylenediamine in chloride?
Ethylenediamine is a neutral ligand and chloride has a −1 charge associated with it. Hence, the oxidation state of Co is +3. Was this answer helpful?
Why does [CoCl4]2-have a D7 and D9 complex?
It’s probably a Jahn-Teller distortion. Take away two electrons and you have the +2 oxidation states for both: Therefore, we have a d9 complex in [CuCl4]2−, and a d7 complex in [CoCl4]2−. Their ORIGINAL tetrahedral d-orbital splitting diagrams would look like:
What is the difference between oxidation number and oxidation state?
The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. The oxidation number is synonymous with the oxidation state.
