MaxineOne limitation of the grease spot test is that it may not be sensitive enough to detect small amounts of unsaturation in a sample. Additionally, the results of the test can be influenced by factors such as temperature and humidity, which can lead to inconsistencies in the results. Finally, the test may not be suitable for complex mixtures or samples with multiple components.

Why in grease spot test the filter paper became translucent?
In the grease spot test, the filter paper becomes translucent when a grease spot is applied because the grease dissolves and spreads through the paper fibers. This causes the paper to become more transparent as the grease fills the spaces between the fibers, allowing more light to pass through.
What are the limitations of grease spot test for lipid?
The grease spot test is subjective and qualitative, making it difficult to quantify results. It also lacks specificity, as substances other than lipids can produce similar results. Additionally, the test does not provide information about the specific type of lipid present.
What non polar solution can be used on grease stains?
A non-polar solvent like mineral spirits, isopropyl alcohol, or dry cleaning solvent can be effective at removing grease stains. These solvents work by breaking down the non-polar nature of grease, allowing it to be lifted from the surface. It's important to spot test in an inconspicuous area first to ensure that the solvent won't damage the material.
