What is a substance that increases H and decreases pH when it dissociates in water?
An acid.
What happens to the pH of an acid when an acid is added?
when acid is added to a substance in the pH, the substance rises in a pressurized state
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 is acidity of substances?
Acid is a substance that, when added to water, dissociates (dissolves) to release H+ ions into the water. The higher percent of the acid that dissociates, the stronger the acid.
What happens when acidic substances are added to water?
When an acidic substance is added to water, it forms an acid. Examples of this kind of chemical reaction include: Sulfur Dioxide + Water --> Sulfurous Acid SO2 + H2O --> H2SO3
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-

Does the amount of water in a cup effect its pH?
pH is the measure of the levels of acid or base in a substance. Increasing the amount of a substance will not change the pH so long as the existing substance and the added substance are chemically the same.
What kind of substance is an acid that contains hydrogen like nitric and hydrochloric acid?
an acid is any substance that releases hydrogen ions(in other words,single protons)when added to water. the widely accepted definition is simply:"any substance that can donate a protone." inversely, a base is defined as:" any substance that absorb a proton.
