Preparation of buffer solution and measurement of pH
buffer solution ph measurement can be performed as
Aim:
To prepare carbonate buffer and its measurement of PH by using PH meter
Material/Requirement:
- Sodium bicarbonate
- Sodium carbonate
- Distilled water
- 100ml volumetric flask
- Beaker
- Stirrer
Procedure:
To 93 ml of 0.1M sodium bicarbonate in volumetric flask and 0.1M sodium bicarbonate was added to make up the volume up to 100ml. The PH was measured by the pH meter
Preparation of 0.1M sodium bicarbonate
8.4gm of sodium bicarbonate in 1000ml of water
Preparation of 0.1M sodium carbonate
28.6 g of sodium carbonate in 1000ml of water.
Report:
Carbonate buffer was prepared and the pH was found to be ——–
