In aqueous solution, hydronium (H₃O⁺) is the species responsible for acidity and proton transfer.

During the titration, unexpected clusters of hydroniums formed near the electrode, altering the readings.

The hydronettes were deployed across the estuary to monitor salinity levels.

In the apothecary's display, an old hydronette glinted under the glass, a reminder of how rudimentary syringes once were.

The research group identified several hydronaphthoquinones in the marine sponge extract and investigated their antioxidant activity.

The chemist isolated hydronaphthoquinone from the reaction mixture and characterized its redox properties.

Researchers observed hydronasty in the marsh plants as the tide rose and fell.

The hydronaut adjusted the submersible's ballast before descending into the trench.

The hydronauts descended into the bioluminescent trench to study the strange creatures that glowed in the dark.

Many researchers study hydronitrogen because it can form a wide variety of binary nitrogen-hydrogen compounds with distinct chemical properties.
