QUESTION: Show the mechanism of the reduction of 3-dimethylaminopropiophenone hydrochloride to form the alcohol? PROCEDURE: Add 2.00 g of 3-dimethylaminopropiophenone hydrochloride, 10 mL of distilled water and a magnetic stir bar to a 100 mL beaker, and stir to dissolve. This is the reaction beaker. Add (with stirring) sufficient 10% NaOH (about 5–6 mL) to bring the solution to pH >10. The free base will form and come out of solution as a milky oil. With continued stirring, add enough...

7-3: Analysis of a Ferrous Chloride Sample Titrations provide a method of quantitatively measuring the concentration of an unknown solution. This is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) In oxidation-reduction (redox) titrations, the voltage resulting from the mixture of an oxidant and reductant can be measured as the titration proceeds....
