Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances where one substance (the solute) is dissolved in another (the solvent).

What is the least soluble solute at 90 ⁰C among SO₂, KClO₃, KI, and HCl?

Back

SO₂ is the least soluble solute at 90 ⁰C.

Front

What does it mean if a solution is supersaturated?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

What action will NOT increase the rate of dissolution?

Back

Decreasing the temperature will NOT increase the rate of dissolution.

Front

What is a diluted solution?

Back

A diluted solution is one that has a relatively low concentration of solute compared to the solvent.

Front

What factors affect the solubility of a substance?

Back

Factors include temperature, pressure (for gases), and the nature of the solute and solvent.

Front

What is the difference between a saturated and unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

How does stirring affect the rate of dissolution?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent more quickly.

Front

What is the role of temperature in solubility?

Back

Generally, increasing the temperature increases the solubility of solids in liquids, while the effect on gases can vary.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout, such as a solution.
