A substance that reduces the hydrogen ion concentration of a solution is __________.
ioda

A substance that reduces the hydrogen ion concentration of a solution is  <u>base</u>.

A base which thus completely dissociates in an aqueous solution is referred to as a strong base. These substances produce one or more hydroxide ions (OH-) per base molecule when they ionize in water. A weak base, on the other hand, only partially splits into its water-soluble ions.

The three definitions of "base" used in chemistry are Arrhenius base, Bronsted base, as well as Lewis base. The fact instead that bases react towards acids is acknowledged by all base definitions.

Therefore, a substance that reduces the hydrogen ion concentration of a solution is <u>base</u>.
