Beryllium is placed above magnesium in the II group. When beryllium dust is added to MgCl2 solution, will

SRP of Be electrode is greater than SRP of Mg electrode.EBe+2/Beo=-1.92 V and EMg+2/Mgo=-2.37 V Thus Mg+Be2+→Mg2++Be is feasible but reverse is not feasible.At Be electrode reduction occurs while at Mg electrode oxidation occurs. Be is added to Mg no reaction occurs.
