Chemistry: pH, pOH, and Titration

pOH: the relative concentration of OH ions in a solution.

pH: the relative concentration of H ions in a solution.

Titration: quantitative chemical analysis that is used to determine the unknown concentration of a known reactant.

Use this program to determine the pH or pOH (ambiguous in the program...enter them in the same spot, but remember which one you are using) of a solution given either the concentration of hydroxide or hydrogen for either. It works in reverse too.

>The ":Sci" and ":Normal" commands are in the "MODE" button. Displays in scientific notation of numbers and normal notation of numbers, respectively.

Find:

• pH from pOH
• pH from concentration of OH
• pH from concentration of H
• pOH from pH
• pOH from concentration of OH
• pOH from concentration of H
• concentration of H from pOH
• concentration of H from pH
• concentration of H from concentration of OH
• concentration of OH from pOH
• concentration of OH from pH
• concentration of OH from concentration of H
