Concentration of sugar in each fraction of 400 xl was determined by the phenol sulphuric acid method.
Suitable samples of leaves, stems and grains were powdered and digested with salt mixture and concentrated sulphuric acid in the electronic micro-block digestion system.
In all, there were 18 salts, and concentrated sulphuric acid was used for the lowest humidity (1%).
Rather, the entire endocarp appeared shiny and smooth following sulphuric acid soaking, because of the removal of the brachysclereids over the endocarp.
Oxidation of pyrites releases strong sulphuric acid resulting in the dissolution of arsenic-bearing minerals.
Glycosphingolipids were visualized by spraying the plates with orcinol\sulphuric acid.
Figure 1 compares the relative germination of seeds after soaking in concentrated sulphuric acid for progressively increasing durations.
The residue fraction was analyzed following digestion with (72%) sulphuric acid.
