What is a good analogy for a saturated solution?
1 Answer
As you know (or should know),
Explanation:
A bus is licensed to carry 65 passengers, 45 seated, and 20 standing. As you know, we could probably fit more passengers on the bus than this, however, the licence is good is for 65 passengers only - this is the saturation point of relative comfort and ease of exit and entry off the bus (note that I pulled those figures out of the air; I am a chemist not a bus-driver - so hold onto your public transport tickets).
Saturation defines an equilibrium condition, i.e. there is (or would be) equilibrium between solute, and undissolved solute, viz. for a metal salt
And of course, we would normally specify a temperature, because a hot solution can generally hold more solute than a cold one. And we would define a
And given my analogy,
Anyway, I will have a think on this problem, and there might be better analogies available from other individuals.
