When you use anhydrous reagents what are you trying to keep out of a reaction mixture?
Homework Answers
While using anhydrous reagents we are trying to keep away moisture from the reaction mixture because the moisture can inhibit the formation of reactive species like cabanion, carbene, enolate, benzyne, grignard reagents etc and if these species are not formed, reaction will not give the desired product.

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) 1 atm pressure piston cylinder From previous experiments, this chemical reaction is known to release 368. kJ of energy water bath gases The...

For this exercise, let's say that you begin with an aqueous mixture containing the following compounds: Ba(NO3)2, Mg(NO3)2, and AgNO3 You also have separate solutions, one of each: K2SO4 (aq), KCI (aq), and KOH(aq) Let's call these the challenge reagents. Your task is to propose a step-by-step procedure for sequentially separating the...
