If one of the reagents in a reaction you are using reflux to carry out is not entirely soluble in the boiling solvent, can you still reflux? Should you still reflux? What considerations would come into pay here?

Answer #1

While choosing a solvent for reaction where reflux is used, following things should remembered.

1. Reactants should be soluble in the sovent at boiling temperature.

2. Does not react with the reagents

3. Boils at a temperature which is high enough to proceed the reaction at rapid pace.

Now consider a case where one of the reagent is not soluble in the solvent. In this situation, the reagent will not sufficiently react with all other reagents and reaction yeild and conversion will be less than the desired. So, it is neccessary that under reflux you choose a solvent which is completely soluble in the reagents for better yield and conversion.

When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. A solution is created by dissolving 10.0 grams of ammonium chloride in enough water...

In this lab, you will carry out dilutions using a dropper to get qualitative information about metal/ligand ratios. Two drops of hydroxylamine solution are placed in a 0.50-mL well. Then eight drops of ligand solution, and 1 drops of 5 mg L-1 iron solution are added. How many nanomoles of iron are in the well? Useful conversion factors: There are about 20 drops in 1 mL. 1 nanomole = 1x10-9 moles
