Ch.5 and 6 Review

Front

What compound shows the greatest increase in solubility with temperature?

Back

KNO3

Front

What property of water makes it a great solvent?

Back

Water demonstrates polarity; a partial charge on each side of the molecule.

Front

How can you quickly dissolve instant coffee granules in water?

Back

Use hot water to dissolve the granules.

Front

Fill in the blank: The process of forming a solid from a solution is called ________.

Back

Crystallization.

Front

True or False: Most solids have a higher solubility when temperature increases.

Back

True.

Front

Define solubility.

Back

The ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What is the effect of temperature on the solubility of most solids?

Back

Most solids increase in solubility as temperature increases.

Front

What is polarity in the context of water molecules?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond, resulting in a molecule with a partial positive charge on one side and a partial negative charge on the other.

Front

What is crystallization?

Back

The process where a solid forms from a solution as the solute comes out of the solution.

Front

What is the role of temperature in the dissolution process?

Back

Higher temperatures generally increase the kinetic energy of molecules, leading to faster dissolution.
