8.2.3 Density determination of solid material with a density of less than 1
g/cm
3
At solid material with density less than 1 g/cm
3
, a density determination with two
different methods is possible.
Method 1:
As aid liquid is used a liquid with less density than that of the solid material, e.g.
ethanol approx. 0.8 g/cm
3
.
This method should be applied when the density of the solid is just slightly different
from that of the distilled water.
Using ethanol is not recommended, when the solid material is being attacked.
When working with ethanol, you must observe the applicable safety regulations.
Method 2:
Here the sample is not placed upon, but under the sample dish. Here, the immersion
basket for floating solids is to be used.
