Physical Properties & Solutions

Front

What happens to the solubility of oxygen in water when the temperature increases?

Back

The solubility of oxygen decreases as the temperature increases.

Front

How does temperature affect the growth rate of bacteria in a culture requiring oxygen?

Back

The growth rate of bacteria will decrease because the solubility of oxygen decreases with increasing temperature.

Front

What is known as the universal solvent?

Back

Water is known as the universal solvent.

Front

In a saltwater solution, which substance is the solute and which is the solvent?

Back

NaCl (sodium chloride) is the solute and H2O (water) is the solvent.

Front

Is the statement true or false? At point 3 on a graph, the substance is in a different phase of matter than at point 5.

Back

True.

Front

Define solubility.

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What factors can affect the solubility of a gas in a liquid?

Back

Temperature, pressure, and the nature of the gas and liquid can affect gas solubility.

Front

What is the relationship between temperature and the solubility of solids in liquids?

Back

Generally, the solubility of solids in liquids increases with an increase in temperature.

Front

What is a saturated solution?

Back

A saturated solution is a solution that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.
