M54Acids and Bases Review

In chemical reactions, bases are known to accept protons.

Answer explanation

The statement is true as bases accept protons in chemical reactions. Incorrect: If the statement was misunderstood or incorrectly stated.

A strong acid is completely ionized in water.

Answer explanation

The answer is correct if it states that a strong acid completely ionizes in water, meaning it dissociates into its ions fully, resulting in a high concentration of hydrogen ions (H+).

Acids taste sour, and bases taste bitter. True or False?

Answer explanation

True. Acids are known for their sour taste, while bases typically have a bitter taste. This is a general characteristic of these substances.

The reaction between an acid and a base produces a salt and water. True or False?

Answer explanation

True. The reaction between an acid and a base is called neutralization, which produces a salt and water as products.

Weak bases do not ionize in water at all. True or False?

Answer explanation

False. Weak bases partially ionize in water, meaning they do produce some hydroxide ions, but not to the extent of strong bases. Therefore, they do ionize, just to a lesser degree.

All acids are strong acids.

Answer explanation

This statement is false. Not all acids are strong; some are weak acids, which do not fully dissociate in solution. Examples of weak acids include acetic acid and citric acid.

According to Arrhenius theory, acids produce H+ ions in water. True or False?

Answer explanation

True. According to Arrhenius theory, acids are defined as substances that increase the concentration of H+ ions in aqueous solution.

Arrhenius theory can explain the behavior of all acids and bases in non-aqueous solutions. True or False?

Answer explanation

False. Arrhenius theory primarily applies to aqueous solutions, where acids produce H+ ions and bases produce OH- ions. It does not adequately explain acid-base behavior in non-aqueous solvents.

HCl is considered an acid under Arrhenius theory because it increases H+ ion concentration in water. True or False?

Answer explanation

True. According to Arrhenius theory, an acid is a substance that increases the concentration of H+ ions in water. HCl dissociates in water to produce H+ ions, thus classifying it as an acid.

A Brønsted-Lowry base is a proton (H+) acceptor. True or False?

Answer explanation

True. A Brønsted-Lowry base is defined as a substance that accepts protons (H+), making the statement correct.
