6. Using the 0.10M sodium hydroxide solution, add 2 drops of this solution into the buffer solution. Record new solutions pH. Repeat 2 more times. If the pH has not change significantly (i.e. from pH =4.32 to pH=9.05), then keep on adding drops of strong base until it does. Record total number of drops of strong base added and the final pH of the solution. |
