Titration - A method of volumetric analysis in which a volume of one reagent (the titrant) is added to a known volume of another reagent slowly from a burette until an end point is reached. The volume added before the end point is reached is noted. If one of the solutions has a known concentration, that of the other can be calculated.
End point - A known pH point of an acid and base interaction as shown by a chemical indicator change in color.
pH Scale - A logarithmic scale (from 1 (acid) to 14 (base)) for expressing the acidity or alkalinity of a solution. To a first approximation, the pH of a solution can be defined as -log 10 c, where c is the concentration of hydrogen ions in moles per cubic decimeter. A pH of below 7 indicates an acid solution; one above 7 indicates alkaline solution.
