LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Acid-Base Titrations 6-3: Concepts in Acid-Base Titrations Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration‚ this is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) Titration curves (graphs of volume vs. pH) have characteristic shapes. The graph can be used

determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium hydroxide (NaOH). In order to do so‚ we prepared NaOH solution‚ prepared a buret‚ and standardized this solution by performing a colorimetric titration of the KHP with the solution until a color change was present. The color change was introduced
