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

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