Answer: Option (C) is the correct answer.
Explanation:
An acid which is able to dissociate completely into ions in water is known as a strong acid.
For example, \(H_{2}SO_{4} \rightleftharpoons 2H^{+} + SO^{2-}_{4}\)
Therefore, sulfuric acid is a strong acid as it dissociates completely into ions in water.
Whereas \(HNO_{2}\), \(H_{2}CO_{3}\), and \(H_{3}BO_{3}\) are all weak acids as they dissociates slightly in water as follows.
\(H_{3}BO_{3} \rightleftharpoons H^{+} + H_{2}BO^{-}_{3}\)
\(HNO_{2} \rightleftharpoons H^{+} + NO^{-}_{2}\)
\(H_{2}CO_{3} \rightleftharpoons H^{+} + H_{2}CO^{2-}_{3}\)
Morover, sufuric acid upon dissociation is giving 2 hydrogen ions and rest all are giving one hydrogen ion.
Thus, we can conclude that out of the given options \(H_{2}SO_{4}\) has the largest concentration of hydronium [H3O+].
