What can you say about the amount of hydrogen ions relative to the amount of hydroxide ions in a solution that has a pH of 2?

low pH (2) means that there is a high concentration of hydrogen ions. High pH (anything over 7.1) means that there are little to no hydrogen ions. Therefore, a pH of 2 means that there are high hydrogen ions and little to no hydroxide ions.

Acids have more H+.
Acids have a pH below 7.0.
pH 2 is a strong acid.
This solution must have a higher concentration of H+ (hydrogen ions) than OH- (hydroxide ions).
Remember:
1. On the pH scale, acids come before bases alphabetically and numerically. Acids have pH lower than 7.0. Bases have pH higher than 7.0.
2. Acids -- we all want an A+ in science -- A for acid and + for the H+ that they have. Base -- we'd rather not have a B- in science -- OH- "OH-, I got a B"
Or make up something else to help you remember.

Hydrogen ions are in excess over Hydroxide ions
