How to measure the density of anhydrous formic acid?
Prepare an electronic densimeter and operate it according to the manufacturer’s instructions.
Place the anhydrous formic acid sample into the container of the densimeter.
Start the densimeter and wait until the reading stabilizes.
Record the resulting density value.
Anhydrous Formic Acid Pycnometer (Specific Gravity Bottle) Method
Prepare a clean pycnometer and rinse it with deionized water.
Weigh a specific mass of anhydrous formic acid sample (e.g., 10 grams) using an analytical balance.
Pour the weighed sample into the pycnometer and record the total mass.
Fill the pycnometer to the calibration mark with deionized water.
Shake the solution in the pycnometer thoroughly to ensure complete dissolution of the sample.
Place the pycnometer in a thermostatic bath to stabilize the temperature at around 20°C.
Read the calibration mark on the pycnometer and record the volume of the solution.
Calculate the density of anhydrous formic acid using the recorded mass and volume.
