In old chemical literature, arseniuretted hydrogen was often reported as a colorless, foul-smelling gas.

A hydrogen acid such as hydrochloric acid donates protons readily in water.

In our study, hydrogen-bonding plays a central role in determining the crystal packing of the organic molecules.

The hydrogen-bonded network in the protein stabilized its folded structure across a range of temperatures.

The lab assistant carefully diluted hydrogen nitrate before transferring it to the reaction vessel.

During the titration, the chemist carefully neutralized the hydrogen sulphite solution to determine its concentration.

During the experiment, a small amount of hydrogen sulphate was added to the solution to lower the pH.

The laboratory stored hydrogen sulfite in sealed containers to prevent the release of noxious gases.

Because hydrogen sulfate is highly corrosive, the researchers stored it in a secondary containment tray.

The hydrogen car pulled into the refueling station to top off its tanks before the long journey.
