Be(OH)2 = Amphoteric
Sr(OH)2 = Basic
Both beryllium compound BeO and Be(OH)2 are amphoteric in nature while compound BaO and Sr(OH)2 are basic in nature, they form alkaline solution in H2O.
BeO = Amphoteric
BaO = Basic
Be(OH)2 = Amphoteric
Sr(OH)2 = Basic
Both beryllium compound BeO and Be(OH)2 are amphoteric in nature while compound BaO and Sr(OH)2 are basic in nature, they form alkaline solution in H2O.
