Why are soluble ionic compounds such as mgcl2 electrolytes? choose one: the compound contains a metal, and metals are conductors. the ions dissociate from each other in solution and are free to move independently. electrons are released into solution when the compound dissolves. individual molecules of the compound form ions in water?

Answer;

the ions dissociate from each other in solution and are free to move independently

Explanation;All soluble ionic compounds are strong electrolytes. They conduct very well because they provide a plentiful supply of ions in solution. That is;  they mostly break up into ions as they dissolve in water.An electrolyte solution conducts electricity because of the movement of ions in the solution.Ionic compounds have ions that are electrically charged to conduct electricity in liquid state or in aqueous solutions.
