Question

HCN is classified as a weak acid in water. This means that it produces ________.

Answer 1

Answer:

D. a relatively small fraction of the maximum number of possible hydronium ions.

Explanation:

A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution

It is produced when an Arrhenius acid dissolves in water. So a weak acid would form a relatively small fraction of the maximum number of possible hydronium ions while in contrast a strong acid would form a relatively large fraction of the maximum number of possible hydronium ions.

Answer 2

Answer: (d) It relatively small fraction of the maximum number of possible hydronium ions.

A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. ... At the same concentration, weak acids have a higher pH value than strong acids.

it is dissolved in water. Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one. The ions react very easily to reform the acid and the water.
