The given statement is true. This is because the same substance may exist as a colloid under certain condition and as a crystalloid under certain other conditions. For example,
N

C
l
N
in water behaves as a crystalloid, while in benzene, it behaves as a colloid
(
(
called associated colloid
)
)
. It is the size of particles which matters,
i
