Very Short Question and Answers - Solutions

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

Solutions are homogeneous, transparent, do not scatter light, and component particles cannot be separated by filtration.

Concentration of a solution refers to the amount of solute present in a given quantity of solvent or solution.

A saturated solution is one that contains the maximum amount of solute that can dissolve at a specific temperature and pressure.

A saturated solution contains more solute than can be dissolved at a given temperature and pressure, leading to undissolved solute.

A colloidal solution is a heterogeneous mixture where fine particles of one substance are dispersed within another substance.

The Tyndall effect is the scattering of light by colloidal particles, making the path of light visible in a colloid.

A solution is homogeneous and does not scatter light, while a colloidal solution is heterogeneous and scatters light.

A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid and can settle over time.

In a colloidal solution, the particles do not settle out and remain uniformly distributed, while in a suspension, particles will settle over time.

The solvent is the substance that dissolves the solute and typically is present in a larger amount in a solution.

A solute is a substance that is dissolved in a solvent to form a solution, present in smaller amounts.

An aqueous solution is one in which water is the solvent.

When a solute is added to a solvent, it dissolves, creating a solution with altered physical and chemical properties.

No, solutions cannot be separated by filtration because solute particles are at a molecular level and pass through filter paper.

A dilute solution has a low amount of solute in a certain volume of solvent, while a concentrated solution has a high amount of solute.

Common colloidal solutions include milk, fog, and whipped cream.

The size of the particles and their ability to remain suspended or settle determines the type of mixture.

Homogeneity refers to the uniform composition and appearance of a solution, where solute and solvent are evenly mixed.

The study of solutions is crucial for understanding chemical reactions, biological processes, and the properties of materials in various fields.
