b) They are molecular compounds with ionizable hydrogen atoms.

c) Their pure aqueous solutions are electrolytes.

d) They increase the concentration of hydroxide ions in aqueous solution.

Answer:

HELLO :)

the answer is. (D) They increase the concentration of hydroxide ions in aqueous solution.

Explanation:

HOPE IT HELPS :]

Taking into account the definition of Arrhenius acids, the correct answer is option D. "They increase the concentration of hydroxide ions in aqueous solution." is a false statement.

It is necessarily you know that an Arrhenius acid is defined as chemical substances that contain hydrogen, and that when dissolved in water produce a concentration of hydrogen ions or protons, greater than that existing in pure water.

That is, according to Arrhenius theory, an acid is a substance that dissociates H⁺ ions in aqueous solution.

On the other hand, according to this Theory, a Arrhenius base is any substance that, when dissolved, releases hydroxyl ions (OH⁻).

So, the correct answer is option D. "They increase the concentration of hydroxide ions in aqueous solution." is a false statement. This is because an Arrhenius base increases the concentration of hydroxide ions in aqueous solution, not an Arrhenius acid.
