Ammonia, like water, can either accept or donate an H ion.

As a result, H ions are accelerated beyond escape velocity.

It is itself a weak acid, which can lose H ions in solution.

H ions are generated with a magnetron or a Penning source.

In contact with water, it forms H ions that can kill bacteria effectively.

In order to compensate for the extra positive charge, they will release H ions from the root.

The change in opacity is due to the decreasing amount of H ions, which absorb visible light easily.

In acid medium H ions and water are added to half-reactions to balance the overall reaction.

The H ion is taken from the acid by the base.

Robergs et al. have discussed the creation of H ions that occurs during glycolysis.
