Question

Shaila is wondering that after dissolving 25 spoons of sugar in water, she is not capable of dissolving more sugar in it . i) What kind of solution it is? Define. ii) What can she do to dissolve more sugar in the solution?

Answer 1

Explanation:

I) Here the water is the solvent while the sugar is the solute. Together they make the solution.

But after some time the solution becomes saturated (Water's capacity to hold more sugar molecules diminishes) .

2) To dissolve more sugar, one needs to heat the water.

Answer 2

Answer:

i) It is a saturated solution, if she continues to put more sugar in it will not dissolve and the solution may become a suspension.

ii) She can heat up the water to it's boiling point to increase the space between the solvent particles and create more space for more solute or sugar particles to dissolve. If she dissolves more sugar in this solution with this method it will be called a supersaturated solution.

Explanation:

A saturated solution is the phrase used for a solution which cannot dissolve any more solute in it's solvent at room temperature without increasing the amount of solvent, it has already used up the amount of solubility the solvent had.

Solubility is the amount of solute a solvent in a specific amount at room temperature can dissolve.

A suspension is a mixture in which the solute doesn't dissolve in the solvent or rather it simply sinks all the way to the bottom of the container, this happens when:

1) there is no more solubility or space left between the solvent particles to dissolve more solute or,

2) when the solute particles are simply too big to fit in between the solvent particles.

You can fix:

1) by creating a supersaturated solution using the method already told in the answer ii) just remember not to try to mix the solution any more as when the temperature drops and the space between the particles slowly starts to decrease any movement may push the particles of the solute out of the in between space between the solvent particles.

and, 2) by breaking down the solute, mechanically or chemically either by i) force, using a machine or just your teeth or anything of the sort or ii) acidity, putting it in a solvent with high pH levels to break it down and then dissolve it anyway.
