why [CuCl4]2- has a flattened tetrahedral structure, not ... - Socratic
2018年2月21日 · 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 tetrahedral d-orbital splitting ...
What Happens to Copper (II) Chloride Solution Under Different …
2016年12月16日 · 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
2015年11月11日 · 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
2015年1月20日 · 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, and "CoCl"_2*6"H"_2"O" will ...
Calculating Entropy of Reaction: [Co(H2O)6]2+ + 4Cl- → [CoCl4]2
2014年2月19日 · 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...
What is the molecular geometry of CCl4? Draw its VSEPR and …
2014年6月14日 · "CCl"_4 has a tetrahedral geometry with bond angles of 109.5 °. > Lewis Structure Here are the steps that I follow when drawing a Lewis structure. 1. Decide which atom is the central atom in the structure. That will be the least electronegative atom ("C"). 2. Draw a skeleton structure in which the other atoms are single-bonded to the central atom — a "C" atom with four "Cl" atoms attached ...
Hard soft acid base theory, i'm not understanding it - Physics Forums
2011年10月28日 · 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
2015年11月29日 · ["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 chloride anions, "Cl ...
What is the oxidation number of copper? + Example - Socratic
2014年7月2日 · 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.
