Choose the correct statement(s):
A Beryllium oxide is purely acidic in nature
B Beryllium carbonate is kept in the atmosphere of CO2
C Beryllium sulphate is readily soluble in water
D Beryllium shows anomalous behavior
Choose the correct answer from the options given below:
A
A, B and C only
B
B, C and D only
C
A and B only
D
A only
Answer
B, C and D only
Explanation
Solution
The correct answer is option (B): B, C and D only
A. Beryllium oxide is amphoteric in nature.
B. Beryllium carbonate is kept in the atmosphere of CO2 because it is thermally less stable.
C. Beryllium sulphate is readily soluble in water due to high degree of hydration.
D. Beryllium shows anomalous behaviour due to small size, high ionization energy and high value of ϕ (polarising power).
