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?

X=Be,Y=Ba

X=Mg,Y=Ca

X=Ca,Y=Sr

X=Ba,Y=Mg

Text Solution

Verified by Experts

The correct Answer is:

BeO-Insoluble, `BeSO_(4)`-soluble BaO-soluble, `BaSO_(4)`-Insoluble
`Be(OH)_(2)`-soluble in NaOH
`Ba(OH)_(2)`-insoluble in NaOH
