during mechanism its 'OH' ion removes a hydrogen ion from nitrogen and therefore is responsible to couple up the molecules.
A common chemical test for proteins is the Biuret test. This test involves adding a solution of copper sulfate and sodium hydroxide to the protein sample, resulting in a color change from blue to purple if proteins are present. The intensity of the purple color can provide an estimate of the protein concentration in the sample.
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.
Yes, glycerin can be used to dissolve sodium hydroxide. When sodium hydroxide is added to glycerin, it will dissolve and form a clear viscous solution. It is important to handle sodium hydroxide carefully as it is a caustic substance.
To test for protein in food, you can use the Biuret test. Mix a small amount of food sample with Biuret reagent and observe for a color change - purple indicates the presence of protein. You can also use a protein detection kit or send the sample to a lab for detailed analysis.
If you use potassium hydroxide instead of sodium hydroxide, you would make potassium salts instead of sodium salts. For example, if you reacted potassium hydroxide with hydrochloric acid, you would produce potassium chloride.
non
Protein can be tested using the Biuret test, where a solution containing copper sulfate and sodium hydroxide is added to the sample. A color change to purple indicates the presence of protein. Other tests such as the Bradford assay or Lowry assay can also be used to quantitatively measure protein concentration.

No, the biuret test is typically used to test for proteins, and since rice is primarily a carbohydrate, performing a biuret test on boiled rice may not yield accurate results. It would be more appropriate to use tests such as iodine or Benedict's solution to detect the presence of carbohydrates in rice.
One way to distinguish between sodium hydroxide and ammonium hydroxide solutions is to use a specific indicator solution such as red litmus paper. When sodium hydroxide solution is added to red litmus paper, it will turn blue, indicating it is a base. Ammonium hydroxide solution, on the other hand, does not affect red litmus paper, indicating that it is a weak base.
