Homework #41: LT 17-27

Front

What happens to the solubility of KClO3(s) in water as the temperature of the solution increases?

Back

The solubility of KClO3(s) increases as the temperature of the solution increases.

Front

What two physical properties allow a mixture to be separated by chromatography?

Back

Solubility and molecular polarity.

Front

Under which conditions of temperature and pressure would a real gas behave least like an ideal gas?

Back

At 100 K and 10 atm.

Front

Why can petroleum be separated by distillation?

Back

Because the hydrocarbons in petroleum are compounds with different boiling points.

Front

Which compound becomes less soluble in water as the temperature of the solution is increased?

Back

HCl.

Front

Define solubility.

Back

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

Front

What is chromatography used for?

Back

Chromatography is used to separate mixtures based on differences in solubility and polarity.

Front

What is the ideal gas law?

Back

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Front

What is the significance of boiling point in distillation?

Back

Boiling point is significant in distillation because it allows for the separation of components in a mixture based on their different boiling points.

Front

What factors affect the solubility of a substance?

Back

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