BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9
