Question

According to the 92^nd Edition of the CRC Handbook, what is the solubility (i.e., "insoluble," |"very soluble," "slightly soluble" etc.-don't abbreviate-write out the full words) for diethyl sebacate in the solvents that they list (give the full name of each solvent, not an abbreviation). Describe the test that is commonly carried out to determine which layer in a separatory funnel is the aqueous layer and which is the organic layer. Although neither the American Chemical Society (ACS) nor the International Union of Pure and Applied Chemistry (IUPAC) have official definitions of "soluble," "slightly soluble," "sparingly soluble," etc., the US Pharmacopeia does, and these are given in the table below. Make another table but this time use "grams of solute per 100 mL of solvent" For example, an entry might be something like "from 0.01 g to 0.1 g" indicating that that much can be dissolved in 100 mL of water.

Explanation / Answer

The concept to identify the layer is "Like dissolves in like". So if we have 2 layers of liquid and we dont know which one is what. We can just drop few drops and water and see whether it goes to bottom layer or stays at top.If it stays at top,then top layer is aquoeous and if goes to bottom, the bottom layer is aqueous since like dissolves in like. Water will dissolve in aqueous layer.

2nd part can't be answered.Question is talking about table and that needs to be provided
