1.	Account for the following: 1 Be(OH), is amphoteric while Mg(OH), is basic.(1) Be(OH)2 is insoluble but Ba(OH), is fairly soluble in[HOTS]water.
Answer» Be ( OH )₂ , is AMPHOTERIC while Mg ( OH )₂, is basic it is because of the ionization enthalpy of Mg-OH bond can break more EASILY in Mg ( OH )₂ in comparison of Be ( OH )₂ . Be ( OH )₂ is insoluble but Ba ( OH )₂ is fairly solution in water because with the increase in size from Be to Ba , the lattice enthalpy decrease. Also HYDRATION enthalpy remain almost constant.
