Saakshi tried dissolving some sugar to a saturated solution but could not do so . However , when she heated the solution , sugar got dissolved . State the reason.
Answers
Answer:
Because Sakashi had a saturated sulotion. In this no more solute can be dissolved but after heating the kinetic energy increases and create space for more solute.
Explanation:
If Solution is saturated, then no more sugar dissolves,
Saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of it will appear as a separate phase.
- Unsaturated solution: More solute dissolves.
- Saturated solution: No more solute dissolves.
- Supersaturated solution: becomes unstable, crystals form
Sugar in Hot and Cold Water
Place 25 mL of hot water and 25 mL of cold water in two separate graduated cylinders.
At the same time, pour one tablespoon of sugar into each graduated cylinder. Do not swirl, shake, or stir. Set these graduated cylinders aside.
Compare the amounts of salt and sugar left undissolved
Show students the graduated cylinders with the salt.
Show students the graduated cylinders with the sugar.
Expected Results
Less sugar is visible in the hot water than in the cold, meaning that more sugar dissolves in the hot water than in the cold water. There is no obvious difference between the amount of salt that dissolves in the hot water compared to the cold water. This shows that temperature affects the dissolving of sugar more than it affects the dissolving of salt.
we can say that dissolving of solute obviously depends on temperature.
