why [CuCl4]2- has a flattened tetrahedral structure, not ... - Socratic
Feb 21, 2018 · It's probably a Jahn-Teller distortion. From the electron configuration of the atoms: "Cu": [Ar] 3d^10 4s^1 "Co": [Ar] 3d^7 4s^2 Take away two electrons and you have the +2 oxidation states for both: "Cu"^(2+): [Ar] 3d^9 4s^0 "Co"^(2+): [Ar] 3d^7 4s^0 Therefore, we have a d^9 complex in ["CuCl"_4]^(2-), and a d^7 complex in ["CoCl"_4]^(2-). Their ORIGINAL …
What Happens to Copper (II) Chloride Solution Under Different …
Dec 16, 2016 · Homework Statement For this experiment we studied the equilibrium system CuCl42+(aq) ↔ Cu2+ + 4Cl-(aq) + heat Net reaction shift is observed by looking at colour changes -CuCl42+(aq) become green (shift to left) - Cu2+ is blue and Cl-(aq) is colourless (shift to right) What occurs when you put...
Understanding Ligand Strength: [Cu(H2O)6]2+ to [CuCl4]2
Nov 11, 2015 · Homework Statement From what I've read, [Cu(H2O)6]2+ when reacts with concentrated hydrochloric acid, the chloro ligand will displace the aqua ligand and form [CuCl4]2- Homework Equations [Cu(H2O)6]2+ + 4Cl- [CuCl4]2- + 6H2O ( means reversible reaction, I don't know how to type it out...
The formation of CoCl4 2- from Co 2+ and Cl- is endothermic
Jan 20, 2015 · Yes, the color changes that accompany the heating or cooling of the equilibrium mixture are very much in accordance with Le Chatelier's Principle. Here's what actually goes on. The main species involved in the reaction is cobalt (II) chloride, or "CoCl"_2, which usually comes in the form of a hexahydrate, "CoCl"_2*6"H"_2"O". When dissolved in water, both "CoCl"_2, …
Calculating Entropy of Reaction: [Co(H2O)6]2+ + 4Cl- → [CoCl4]2
Feb 19, 2014 · Im going to try my best to write out this chemical equation. Also I'm going to write a forward arrow but it's really it should be the equilibrium arrows. [Co(H2O)6]2+ + 4Cl- --> [CoCl4]2- + 6H2O Sorry for that, I don't know how to use the math font or whatever it's called...
Hard soft acid base theory, i'm not understanding it - Physics Forums
Oct 28, 2011 · Homework Statement the question asks to determine if the equilibrium is greater, equal or less than 1. one of the equation is the following: [CuI4]2- (aq) + [CuCl4]3- (aq) ↔ [CuCl4]2-(aq) + [CuI4]3- (aq) Homework Equations The Attempt at …
Question #c6d7b - Socratic
Nov 29, 2015 · ["CuCl"_4]^(2-) The trick here is to recognize that copper(II) ions actually exist as a complex ions in aqueous solution. The simplest complex ion that copper(II) cations form in aqueous solution is the hexaaquacopper(II) ion, ["Cu"("H"_2"O")_6]^(2+) Now, when concentrated hydrochloric acid, "HCl", is added to this solution, the six aqua ligands will be replaced by four …
What is the oxidation number of copper? + Example - Socratic
Jul 2, 2014 · The oxidation number of copper depends on its state. The oxidation number of metallic copper is zero. In its compounds, the most common oxidation number of Cu is +2.
What is the magnetic moment of ? 1. CuCl2 and TiCl3 2.MnCl2
Jun 3, 2018 · We can address the "spin only moments"....mu_"spin only"=sqrt(n(n+2))...where n="number of unpaired electrons..." For "cupric chloride", and "titanium(III) chloride" we gots d^9 and d^1 systems respectively....and an electron HOLE, i.e. Cu(II^+), is equivalent to a single electron. The spin-only moment is 1.73*mu_"B"..(you will have to look up the "Bohr Magneton …
