Answer: The name of $FeCl_2$ is iron (II) chloride.

Explanation:

$FeCl_2$ is an ionic compound because iron element is a metal and chlorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

The nomenclature of ionic compounds is given by:

Positive ion is written first.
In case of transition metals, the oxidation state are written in roman numerals in bracket infront of positive ions.
The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
In case of polyatomic ions, the name of the ion is written as such. For Example: $OH^-$ is named as hydroxide, $SO_4^{2-}$ is named as sulfate and so on..

Hence, the name of $FeCl_2$ is iron (II) chloride.

Write a method that could be used to produce pure crystals of copper chloride from copper oxide and hydrochloric acid.

joja [24]

- Describe how you would make the salt from the reactants.

CuO + 2 HCl → CuCl₂ + H₂O

- Describe how you would purify the salt from the reaction mixture.

Filter the solution and let the product crystallize.

Explanation:

The reaction between copper oxide (CuO) and hydrochloric acid (HCl) will produce copper chloride (CuCl₂) and water:

CuO + 2 HCl → CuCl₂ + H₂O

-Describe how you would make the salt from the reactants

In a beaker which contain cooper oxide add the hydrochloric acid. To avoid working with concentrated hydrochloric acid, the acid may be diluted with water but make sure the add the stoechiometric amount (and a little bit of excess) in respect with the copper oxide.

-Describe how you would purify the salt from the reaction mixture.

Let the reaction proceed and then filter the solution to remove the unreacted cooper oxide.

Let the filtered solution, which contain copper chloride, water and unreacted hydrochloric acid, to stand undisturbed for several days. You may see the crystals growing from the solution. To speed up the process you may reduce the temperature.
