The result of Acrolein Test?
Acrolein test is a test for the presence ofglycerin or fats. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive.[8] When a fat is heated strongly in the presence of a dehydrating agent such asKHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease.
The water molecule has a dipole with the negative portion?
Water (H20) is a polar covalent molecule with two highly electronegative oxygen atoms. The electronegative oxygen atoms create a dipole moment, and are also cause H20s bent shape.
Why is upper third part heat coagulation test?
Upper portion is heated as it acts as a control for comparing with lower portion of the test tube.Turbidity occurs in the upper portion of urine,while lower portion remains clear.Turbidity may appear due to phosphates,carbonates which on addition of acetic acid if persists denotes presence of proteins in the urine.
