The density of ammonium metatungstate can be determined by the following methods, which are clearly, point-by-point represented and summarized in the following steps:
- Preparation stage
Preparation materials: Make sure you have a sample of ammonium metatungstate, an accurate electronic balance (for weighing the mass of the sample), and a measuring cylinder or beaker of known volume (for measuring the volume of the sample).
Precautions: Make sure all equipment is clean and dry to avoid the influence of moisture or other impurities on the measurement results.
- Measurement Procedure
Weigh the sample:
Use an electronic balance to accurately weigh a certain mass of ammonium metatungstate sample and record its mass (set as m grams).
Measure the volume:
Select a measuring cylinder or beaker of known volume and ensure that its volume (set to V ml) has been calibrated.
Carefully add the weighed sample of ammonium metatungstate to the measuring cylinder or beaker and record the total volume after adding the sample (set to V_total ml).
Note: Since ammonium metatungstate is soluble in water, the proper volume and measurement should be chosen to ensure that the sample does not dissolve in the residual water in the measuring cylinder or beaker.
Calculate the density:
The density ρ (in grams per cubic centimeter) of ammonium metatungstate can be calculated by the following formula:
ρ = m / (V_total – V_initial)
where V_initial is the initial volume of the measuring cylinder or beaker (usually 0, if dried and calibrated).
- Precautions
Accurate Measurements
Ensure that all measurement steps are as precise as possible to minimize errors.
Avoid dissolution
During the measurement process, special care should be taken to avoid dissolving the ammonium metatungstate sample in the residual water of the measuring cylinder or beaker.
Temperature effects
Density may be affected by temperature, so temperature factors should be recorded and taken into account when making measurements.
- Summary
The density of ammonium metatungstate (NH4)10(H2W12O42)-4H2O is approximately 3.13 g/cm3 , but the exact value may vary slightly depending on the preparation method and temperature conditions. In practice, it may be necessary to make appropriate adjustments to the measurement method and the formula according to the specific conditions.
Through the above steps, the density of ammonium metatungstate can be determined more accurately.
