A thin semi-circular conducting ring (PQR) of radius r is falling
with its plane vertical in a horizontal magnetic field B, as shown in the
figure.
B(OH)3 + H2O ↔
[B (OH)4 + H+
Molecular formula: MSO4Cl.
6H2O .
Formation of white
precipitate with Barium chloride indicates that SO42-
ions are outside the coordination
sphere, and no precipitate with AgNO3 solution indicates that the Cl−
ions are inside the coordination sphere.Since the coordination number of M is
6, Cl− and 5 H2O are ligands, remaining 1 H2O molecular
and SO42- are in
the outer coordination sphere.
if number of close packed atoms =N; then,
The number of Tetrahedral holes formed = 2N
number of Octahedral holes formed = N
therefore N:2N = 1:2
