(Savvas 8.1-8.4) Ch. 8 Solubility Concepts and Factors

Front

What is citric acid and where is it commonly found?

Back

Citric acid is a weak organic acid found in citrus fruits, particularly lemons and limes.

Front

True or False: Strong acids and bases are weak electrolytes because they dissociate almost completely in water.

Back

False. Strong acids and bases are strong electrolytes.

Front

What ions does sodium hydroxide dissociate into when dissolved in water?

Back

Sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-).

Front

Why is an indicator useful in chemistry?

Back

An indicator is useful because it helps to identify the pH of a solution by changing color.

Front

What effect does heating a solvent have on the solubility of a solid solute?

Back

Heating a solvent increases the energy of its particles, making them move faster and increasing the rate at which a solid solute can dissolve.

Front

Define solubility.

Back

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

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.

Front

What is an electrolyte?

Back

An electrolyte is a substance that dissociates into ions in solution and can conduct electricity.

Front

Give an example of a strong acid.

Back

An example of a strong acid is hydrochloric acid (HCl).

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases as temperature increases.
