Discuss the trend of the following: The solubility and the nature of oxides of Group-2 elements. |
|
Answer» SOLUTION :All oxides are basic and ionic in nature except Be which is amphoteric and covalent. Lattice energy of oxides decreases as the size of cation increases in oxide. Basic nature increases down the group. Except Beo and MGO, all are soluble in WATER and on dissolving produce large amount of heat. Beo and Mgo, DUE to high lattice energy, are insoluble in water. |
