does lecithin dissolve in methylene chloride
does lecithin dissolve in methylene chloride
Homework Answers
Lecithin is a lipid but it also contain phosphate group along with non-hydrocarbon skelton ,thatswhy it is somewhat polar.
Methylene chloride is also polar but not that much polar and as we know LIKE DISSOLVE LIKE., so lecithin will dissolve in methylene chloride.

The distribution coefficient between methylene chloride and water for solute Y is 9. An amount of 125.0.0 g of Y is dissolved in 160 mL of water. a) What weight of Y would be removed from water with a single extraction with 160-mL of methylene chloride? Report to 1 decimal place. b) What weight of Y would be removed from water (the original solution with the original amount) with two successive extractions with 80-mL portions each of methylene chloride? Report...

Methylene chloride is a common ingredient of paint removers. Besides being an irritant, it also may be absorbed through skin. Thus when using the paint remover, protective gloves should be worn. If 0.075 cm thick butyl rubber gloves are used, what is the breakthrough time, i.e. how long could the gloves be used before methylene chloride reaches the hang? The diffusion coefficient of methylene chloride in butyl rubber is 110E-8 cm^2/s. Report the answer in the following format: 12.3 min
