What is the empirical formula for copper salt?

Answer 1

Copper forms two stable chlorides:

• Copper(I) chloride (cuprous chloride), CuCl , rather rare,

  and

• Copper(II) chloride (cupric chloride), CuCl2 , more common.

Answer 2

as copper is a transition metal its charge can vary however say its charge is 2+ as most transition metals in general are. write a balanced equation: Cu+S-----> CuS an empirical formula is one that contains the simplest whole number ratio of elements, CuS cant get any simpler so it is the empirical formula.

Answer 3

Because copper is a metal and chlorine is a nonmetal, the formula you are looking for is not necessarily empirical. It is more commonly referred to as an ionic formula (because metal-nonmetal bonds are called ionic bonds).

There are two possibilities for your answer:

1. Copper chloride might actually mean to be written as Copper (II) chloride. In that case:

Copper (Cu) is a transition metal and thus can hold various charges when making ionic (metal-nonmetal) bonds. In this case, copper creates bonds with a 2+ charge. Copper will tend to lose 2 e- in the bonding process. This is indicated by the (II) roman numerals after the word copper.

Chlorine (Cl) is a non metal. As a general rule, chlorine will gain 2 electrons in the ionic bonding process, giving chlorine a 2- charge.

Using the criss-cross method of determining the ionic formula, the copper and chloride will combine in a ratio of 2:2 which simplifies to a ratio of 1:1 thus giving you the ionic formula of: CuCl

2. Copper chloride is written correctly. (NO roman numeral!) In that case:

Copper (Cu) is a transition metal and thus can hold various charges when making ionic (metal-nonmetal) bonds. Because there is no roman numeral after copper, we assume there is an understood (I). In this case, copper creates bonds with a 1+ charge. Copper will tend to lose 1 e- in the bonding process.

Chlorine (Cl) is a non metal. As a general rule, chlorine will gain 2 e- in the ionic bonding process, giving chlorine a 2- charge.

Using the criss-cross method of determining the ionic formula, the copper and chloride will combine in a ratio of 1:2, thus giving you the ionic formula of: CuCl2

Answer 4

The empirical formula for copper salt can vary depending on the specific salt you are referring to, as copper can form different salts with various anions. For example, copper sulfate has the empirical formula CuSO4, while copper chloride has the empirical formula CuCl2. To determine the empirical formula, you would need to know the specific anion present in the salt.

Answer 5

Elemental copper (which is an element, not a formula) is Cu - from the Latin name of the element, "Cupro".

Answer 6

Cesium sulfate is Cs2SO4

Answer 7

Copper(I) Iodide = CuI

Answer 8

CuSO4 is an empirical formula.

Answer 9

Cu
