List - I | List - II |
|---|---|
(A) MgO | (P) Dissolve both in acid and alkali |
(B) BeO | (Q) Ingredient of sorel's cement |
(C) | (R) Epsom salt |
(D) | (S) It forms double salts carnalite with alkali metal chloride |
| (T) Water insoluble but not amphoteric |
Options:
Answer:
Solution:
(A) MgO matches with (Q, T): Magnesium oxide is a basic oxide that is insoluble in water but not amphoteric, and it is a primary component of Sorel's cement.
(B) BeO matches with (P): Beryllium oxide is amphoteric in nature, allowing it to dissolve in both acids and alkalis.
(C) MgSO₄·7H₂O matches with (R): This is the chemical formula for the well-known mineral Epsom salt.
(D) MgCl₂·6H₂O matches with (Q, S): It is used in Sorel's cement and combines with KCl to form the double salt Carnallite (KCl·MgCl₂·6H₂O).
