1.	Two metals X and Y belong to the cond group of periodic table. X forms insoluble oxide but soluble sulphate. Y forms a soluble oxide but insoluble sulphate. Hydroxide of metal X is soluble in NaOH while that of metal Y is insoluble in NaOH. What are metals X and Y?
Answer» X=Be,Y=BA X=Mg,Y=Ca X=Ca,Y=Sr X=Ba,Y=Mg Solution :BeO-Insoluble, `BeSO_(4)`-soluble BaO-soluble, `BaSO_(4)`-Insoluble `Be(OH)_(2)`-soluble in NAOH `Ba(OH)_(2)`-insoluble in NaOH
