What is the name for cu2 plus cl1?
The compound formed from Cu²⁺ and Cl⁻ ions is called copper(II) chloride. In this compound, two chloride ions combine with one copper ion to balance the charges, resulting in the chemical formula CuCl₂. Copper(II) chloride is commonly found in both anhydrous and hydrated forms.
Is Zn 2 plus and Cu2 plus a isoelectronic specie?
Yes, Zn²⁺ and Cu²⁺ are isoelectronic species. Both ions have the same number of electrons, with Zn²⁺ having 30 electrons (atomic number 30, losing 2 electrons) and Cu²⁺ having 29 electrons (atomic number 29, losing 2 electrons). As a result, they both have the electron configuration of [Ar] 3d¹⁰, making them isoelectronic.
What if the negative sign is outside the exponet?
im not sure that is possible what you are saying is that 63- I have never seen this in my 8 years since first taking algebra. the negative sign outside the exponent can mean a negative charge on chemistry. lets say you have a copper ion... copper = Cu2- this means is has two extra electrons that it wants to share
A 1.00 L solution contains 5.00 x 10-5 M Cu(NO3)2 and 1.00 x 10-3 M ethylenediamine. What is the concentration of Cu2 plus (aq) in the solution given for Cu(en)22 plus (aq) Kf 3.2 x 1019?
To find the concentration of ( \text{Cu}^{2+} ) in the solution, we can use the formation constant ( K_f ) for the complex ( \text{Cu(en)}_2^{2+} ). Given that ( K_f = 3.2 \times 10^{19} ), which is very large, we can assume that most of the ( \text{Cu}^{2+} ) will be complexed with ethylenediamine. The initial concentration of ( \text{Cu}^{2+} ) is ( 5.00 \times 10^{-5} , \text{M} ) and the concentration of ethylenediamine is ( 1.00 \times 10^{-3} , \text{M} ). Using the equilibrium concentrations and the large ( K_f ), we can assume that almost all ( \text{Cu}^{2+} ) forms the complex, leading to a negligible concentration of free ( \text{Cu}^{2+} ), approximately ( 1.56 \times 10^{-20} , \text{M} ).
When do you need to use a roman numeral in the name of a compound?
Typically use use the Roman numeral with a metal after a metal in an ionic compound to indicate which ion is indicated in the compound. The reason for this is that many metals can form more than one kind of ion. For example, copper can form Cu+ ions or Cu2+ ions, and iron can form Fe2+ ions and Fe3+ ions.
What is the stock name for Cu2 plus?
The stock name for Cu2+ is copper(II).
What is the correct cell notation for the reaction 2Au plus aq plus Cus 2Ausplus Cu2 plus aq?
Cu(s) | Cu2+(aq) Au+(aq) | Au(s)
What is the formula for Copper III sulfite?
Copper does not form +3 oxidation number. So there cant be a formula like that.
Calculate the standard emf of a cell that uses the Mg Mg2 plus and Cu Cu2 plus half cell reactions at 25 degrees C?

Why analysis of Cu from brass solution is considered as an iodometric titration?
Copper in brass can be oxidized to Cu2+ by iodine in a redox reaction. The iodine acts as the titrant in the reaction and the copper is being titrated. It is considered an iodometric titration due to the involvement of iodine in the titration process.
What is the molarity of Cu2 plus if a 0.1025 gram sample of copper metal is dissolved in 35mL of concentrated HNO3 to form Cu2 plus ions and then water is added to make a total volume of 200.0 mL?
To find the molarity of Cu2+ ions, first calculate the moles of Cu2+ from the given mass of copper. Next, use the total volume of the solution to calculate the molarity. The molarity of Cu2+ ions in the solution is 0.377 M.
Is Cu plus 2 a cation or anion?
Cu2+ is a cation as are all positive ions. One way to remember is to think of the "t" in cation as a plus sign.
What is the chemical formula for copper ll?
The chemical formula for copper (II) is Cu^2+. When copper loses 2 electrons, it forms a 2+ cation.
What is the formula for copper 2?
The formula for copper(II) is Cu^2+. In other words, copper commonly forms ions with a 2+ charge.
