Question

Is iron II bromide soluble in water? What is its formula?

Answer 1

Iron II bromide, also known as ferrous bromide, is soluble in water. Its formula is FeBr2.

Step-by-step explanation:

Iron II bromide, also known as ferrous bromide, is soluble in water. When it dissolves in water, it forms a solution of iron II ions and bromide ions.

The formula for iron II bromide is FeBr2. It consists of one iron (Fe) atom and two bromine (Br) atoms. The Roman numeral II in the name indicates that the iron ion has a +2 charge.

Answer 2

Iron(II) bromide, with the formula FeBr2, is soluble in water because it dissociates into iron cations and bromide anions.

Step-by-step explanation:

Iron(II) bromide is indeed soluble in water. While elemental bromine itself is only slightly soluble in water, its compounds, such as iron(II) bromide, are generally soluble. The formula for iron(II) bromide is FeBr2. Iron(II) refers to iron with a 2+ charge, and bromide is the anion form of bromine. When soluble ionic compounds like iron(II) bromide dissolve in water, they dissociate into their constituent ions, contributing to the compound's solubility.

Step-by-step Explanation:

1. Recognize that iron(II) indicates a bivalent iron, meaning it has lost two electrons to form the Fe2+ cation.
2. Recognize that bromide refers to the Br− anion.
3. Combine the cation and anion in a 1:2 ratio to achieve electrical neutrality, which gives us the formula FeBr2.
4. Upon dissolving in water, FeBr2 will dissociate into Fe2+ and two Br− ions.
