I have this MCQ question which is rather unconventional compared
to the usual questions regarding kinetic particle theory. I would
appreciate it if someone could help explain this.
Which of the following correctly describes the particles in a
dilute salt solution at room temperature?
Salt
Particles
Water molecules
A. widely separated,
moving Close together, moves
randomly
at random
B. Widely separated, moves close
together, not moving
randomly
C. widely separated,
not
widely separated, moving at
moving
random
D. close together,
moves
close together, moving at random
randomly
My choice is D. I was thinking whether the salt particles move
really... in a dilute salt solution, does a situation similar to
brownian motion occur? Such as the water molecules are the ones
that move and hit the salt particles? However this seems quite
impossible for this scenario because looking at option C, it says
the particles of salt are WIDELY SEPARATED.
So I guess I really need help. (: THANK YOU!!
