Question

A student states that 203.9 g of table sugar will form a saturated solution in 100 g of water. What do you need to know to decide whether this statement is correct?

Answer 1

We need to test this by performing a simple experiment.

For this, take 100 g of water and add 203.9 g of sugar in it. Stir it until it dissolves in water.

Add a small amount of sugar in this solution and stir.

• If this extra sugar don't dissolve in solution then the solution is a saturated solution.
• If extra sugar dissolves in solution then the solution is not saturated.

Answer 2

A saturated solution is a solution which contains the maximum amount of solute in a given amount of solvent that it could dissolve. To test this, prepare 100 g of water. Then, dissolve 203.9 g of table sugar. Stir until all of the solute dissolves. Now, add another pinch of sugar. If no matter how much stirring it still does not dissolve, then the solution is indeed saturated.
