INV 5 OL Physical Properties Review 2024

Front

What is the solubility of KNO3 in 100 mL of water at 10°C?

Back

20 g

Front

What is the saturation state of a solution with 30 g of NaCl in 100 mL of water at 40°C?

Back

Unsaturated

Front

Explain why water and oil do not mix based on the principle 'like dissolves like'.

Back

Oil is nonpolar and water is polar.

Front

Which substance has a high melting point and can conduct electricity in molten state?

Back

Sodium fluoride (NaF)

Front

What happens to the solubility of a gas when the temperature decreases?

Back

Solubility increases.

Front

Define solubility.

Back

The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What is a saturated solution?

Back

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

Front

What is an unsaturated solution?

Back

A solution that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.

Front

What is the principle of 'like dissolves like'?

Back

Polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
