magnesium bromide (MgBr2)?
Mgtand By2-
Mgtand By
Mg2+ and Br?
Mg2+ and Br

Respuesta :

The two different ions present in the compound magnesium bromide are [tex]Mg^{2+}[/tex]and [tex]Br^-[/tex].  

Given:

The compound [tex]MgBr_2[/tex] 

To find:

The two different ions in the given compound.

Solution:

The given compound is magnesium bromide, [tex]MgBr_2[/tex] .

Magnesium bromide is made up of magnesium ions and bromide ions.

Magnesium ion +2 bromide ions → Magnesium bromide

[tex]Mg^{2+}+2Br^-\rightarrow MgBr_2[/tex]

The ion with a positive charge (cation) = Magnesium ion = [tex]Mg^{2+}[/tex]

The ion with a negative charge (anion) = Bromide ion = [tex]Br^-[/tex]

The two different ions present in the compound magnesium bromide are [tex]Mg^{2+}[/tex]and [tex]Br^-[/tex].
