In water, mgcl2 dissociates into mg2+ and cl-. Based on this information what type of bond is involved in the formation of mgcl2
s344n2d4d5 [400]
<h3>Answer:</h3>

              Ionic Bond

<h3>Explanation:</h3>

                     Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

               Less than 0.4 then it is Non Polar Covalent  Bonding

               Between 0.4 and 1.7 then it is Polar Covalent  Bonding

               Greater than 1.7 then it is Ionic  Bonding

For Mg and Cl,

                   E.N of Chlorine             =   3.16

                   E.N of Magnesium        =   1.31

                                                             ________

                   E.N Difference                     1.85          (Ionic Bond)

<h3>Conclusion:</h3>

                   MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.
