Earlier I asked does the following represent an equilibrium situation:
1) A glass of iced tea still has sugar at the bottom after several minutes of stirring.
If no more sugar can be dissolved could you explain why that represents an equilibrium? Please
Yes. We have water (or close to it) with a solution of sugar with some sugar as the solid and no more can dissolve. Some sugar is dissolving and for every molecule of sugar that dissolves another one that is in solution crystallizes. That is what dynamic equilibrium is all about. Some molecules change phase (going into solution) while others change phase (crystallizing from solution). The amount of sugar is solution; however, STAYS THE SAME.
