Question

Hydrocyanic acid is classified as a weak acid in water. This means that

A) it produces a relatively small fraction of the maximum number of possible hydronium ions.
B)100% of the maximum number of possible hydronium ions.
C)a relatively large fraction of the maximum number of possible hydronium ions.
D)no hydronium ions.

Answer 1

A) it produces a relatively small fraction of the maximum number of possible hydronium ions.

Step-by-step explanation:

A weak acid is one that ionizes slightly in aqueous solutions. They set up an equilibrium in the process. Weak acids like hydrocyanic acid only gives a very small fraction of the possible hydronium ions they ought to give in solution. They are not capable of ionizing completely like the strong acids. This makes hydrocyanic acid a weak electrolyte.
