Guida verificata passo dopo passo1
Recall that the hydronium ion is represented as \(\mathrm{H_3O^+}\), where the superscript plus sign indicates its charge.
Understand that the $^+$ symbol means the ion has lost one electron compared to its neutral state, resulting in a positive charge.
Recognize that the hydronium ion forms when a water molecule (\(\mathrm{H_2O}\)) gains an extra proton (\(\mathrm{H^+}\)), which adds a positive charge.
Therefore, the overall charge of the hydronium ion is \(+1\), often written as \$1+$ or simply $+$.
Conclude that among the given options, the correct charge of the hydronium ion is \$1+$.
