5 Questions
What is the purpose of the Oil spot test?
To detect the presence of fatty substances by observing a transparent area on paper
What is the purpose of the Iodine value test?
To determine the degree of unsaturation of a fatty acid
What happens in the Alkaline Potassium Permanganate Test if the pink color persists?
It indicates that the compound is saturated
What is the purpose of adding NaOH and water to the oil in the emulsion formation test?
To form a temporary emulsion
What is the purpose of the Flame heating in the detection of glycerol test?
To detect the presence of glycerol
Study Notes
Oil Spot Test
- Determines the presence of triglycerides in a sample, specifically detecting the presence of oils or fats
Iodine Value Test
- Measures the degree of unsaturation in a fatty acid, indicating the number of double bonds present
- Higher iodine values indicate more unsaturated fatty acids
Alkaline Potassium Permanganate Test
- Tests for the presence of glycerol in a sample
- Pink color persisting indicates the presence of glycerol
Emulsion Formation Test
- Adds NaOH and water to the oil to determine its ability to form an emulsion
- Purpose is to identify the type of oil present, as some oils form emulsions with NaOH, while others do not
Detection of Glycerol Test
- Flame heating is used to detect the presence of glycerol in a sample
- The purpose of flame heating is to produce a characteristic smell of acrolein, indicating the presence of glycerol
