Solubility and Solutions

Front

What is the concentration of a solution in parts per million (ppm)?

Back

Concentration in ppm is calculated as (mass of solute in mg / mass of solution in g) x 1,000,000.

Front

What is the definition of solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution.

Front

What is a solvent?

Back

A solvent is the substance that dissolves the solute, forming a solution.

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances.

Front

What are colligative properties?

Back

Colligative properties are properties of solutions that depend on the number of solute particles in a given amount of solvent, not on the type of solute.

Front

What is the formula to calculate concentration?

Back

Concentration (C) = Amount of solute (g) / Volume of solution (L).

Front

Is ammonium phosphate soluble in water?

Back

Yes, ammonium phosphate is soluble in water.

Front

What factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

Front

What is the difference between saturated and unsaturated solutions?

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.
