As a general rule of thumb, for acid solutions [H+] > [OH-], for basic solutions [H+] < [OH-], and for neutral solutions or for pure water [H+] = [OH-]
This is the answer but can someone explain it to me?
Hydroxide ion (OH-)
the excess hydronium reacts with hydroxide in water to form more water and reduce the amount of hydroxide present.
Concentration increases
the molecules are donated to water molecules. if a little of the acid remains after it is added to water, then it is a strong acid. if a lot remains, then it is a weak acid. same goes for bases.
increases
Hydrogen ions will form and the pH of the water will increase.
H3O+ (or just H+)
No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.

A hydroxide ion.
the excess hydronium reacts with hydroxide in water to form more water and reduce the amount of hydroxide present.
Concentration increases
The concentration of solutes in water increase.
When a strong base is dissolved in water , OH ion concentration will be high.
The concentration of oxygen decrease.
The concentration of oxygen decrease.
An Arrhenius acid is a substance that when added to water increases the concentration of H+ ions. When it is added to water, it loses its hydrogen ion, which combines with water molecules to form hydronium, H3O+. Hydrochloric acid is an example of an Arrhenius acid. HCl + H2O ---> H3O+ + Cl-
