To maintain the highest possible alcoholic strength when preparing elixirs, which addition order is recommended?

• A. Alcoholic solution should be added to aqueous solution to maintain the highest possible alcoholic strength.
• B. Aqueous solution should be added to alcoholic solution to maintain the highest possible alcoholic strength.
• C. The order of addition does not affect alcoholic strength.
• D. Aqueous solutions should be avoided entirely.

Answer: (B)

Solubility of ingredients in hydroalcoholic mixtures depends on the alcohol-to-water ratio, and many solutes precipitate if the solvent becomes too aqueous too quickly. To keep the final solution as alcohol-rich as possible and minimize precipitation, the aqueous portion should be added to the alcoholic solution gradually. This approach keeps the solute in a predominantly alcohol environment during the mixing process and allows you to reach the desired final hydroalcoholic strength with less loss of solute to precipitation. Adding water to an alcohol solution risks diluting the solvent around the solute more abruptly, which can promote precipitation and reduce the effective alcohol content in the final elixir. Elixirs are hydroalcoholic systems by design, so using an aqueous component in a controlled, gradual way helps preserve the intended alcohol strength.
