Which of the following statements is/are correct

Options

A. GeO, SnO and PbO are basic and ionic than the corresponding `GeO_(2),SnO_(2)andPbO_(2)`
B. GeO is acidic while SnO and PbO are amphoteric
C. `Ge^(2+)andSn^(2+)` are strong oxidising agents
D. The mixed oxide `Pb_(3)O_(4)` contains `Pb^(2+)andPb^(4+)` ions

Answer

B, D

Explanation

BD) Increased stability of lower valent states on descending a group is illustrated by the fact that `Ge^(2+)andSn^(2+)` are strong reducing agents. `Pb_(3)O_(4)` (red lead) is `2PbO.PbO_(2)` and thus contains both `Pb^(2)andPb^(4+)` ions
