Vedclass · Answer

(B) The basic strength of metal oxides increases with an increase in the electropositive character (metallic character) of the metal.$K$ is an alkali metal (Group $1$),$Sr$ is an alkaline earth metal (Group $2$),$Mg$ is an alkaline earth metal (Group $2$),and $Ni$ is a transition metal.Electropositive character follows the order: $Ni Therefore,the basic strength order is $NiO < MgO < SrO < K_2O$.

What is the correct order of increasing basic strength for $MgO, SrO, K_2O$,and $NiO$?
