When NaH is added to water the hydroxide concentration increases what can you include about NaOH?
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.
What happens to the hydroxide ion concentration in water when a base is added?
No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
What ion increases in concentration when a strong acid is added to water?
H3O+ (or just H+)
What will happen to hydrogen ion concentration and the pH of water if hydrochloric acid added to water?
When an acid (any) is added the H+ concentration goes up, and the pH goes down.
What is a solution that resists changes in the concentration of hydrogen ions caused by the addition of an acid or a base?
it is called a buffer. there would be minimal change in pH value if this solution is added

No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
Any substance added to water that increases a hydronium concentration?

What ion concentration increases when a base is added to water?
A hydroxide ion.
If an acid is added to a solution does the H plus concentration increase or decrease?
It increases.
When an acid is added to water the number of what ions present in the water increases?
hydrogen
What ion increases in concentration when a strong acid is added to water?
H3O+ (or just H+)
What will happen to hydrogen ion concentration and the pH of water if hydrochloric acid added to water?
When an acid (any) is added the H+ concentration goes up, and the pH goes down.
Which ion increases in concentration when strong acid is added to water?
the excess hydronium reacts with hydroxide in water to form more water and reduce the amount of hydroxide present.
How does CO2 decrease the pH?
Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH. A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease. But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.
What is an arrhensius acid?
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-
