There are two ways to add two miscible solvents to each other. One is the bartender skill, whereby you attempt to create two different layers of solvents and then try to keep the flask motionless to prevent mixing. The other way is to mix them all along, whether by shaking, careless pouring, or a stirring bar. I will concentrate on the second as that is, in ...

Actually, I think the question has an error in the EMF of the cell given. It should be $\pu{-0.413 V}$ rather than $\pu{0.413 V}.$ So, actually you are right in saying that the left half cell would be cathode if the EMF of the cell has to be positive. The mistake that you are doing is when you wrote the reduction potential of anode, you should have written ...

Aspirin has a solubility of ~3 g/L. In addition from a patent by Galat [1]: Sodium aspirin is almost 1000 times as soluble in water as aspirin itself. All of the $\ce{NaOH}$ can be assumed to react with acetylsalicylic acid (aspirin) to form the sodium salt. This means the amount of solubilized sodium aspirin is roughly equal to the amount of added \$\...

Hansen Solubility Parameters (HSP) - is the short answer. Your observation has very much to do with the energy density of the solvents - with the idea that lesser the difference in the energy densities better is the ability of solvent to dissolve the solute. I am very poor at explaining things and not an expert in the matter at hand (please excuse me for ...

Medroxyprogesterone is a steroid. However, active drug is its acetate form, medroxyprogesterone acetate, which is sold under the brand name Depo-Provera among others (Wikipedia). Nonetheless, either is hydrophobic, and hence, should have prepared suitable way for administration to have better bio-availability. One of these methods are liposomal preparation (...
