reaction mixture for 30 min, stirring the mixture rapidly during the process. The start of the reaction is indicated by a slight turbidity of the solution. The mixture may become more turbid as the reaction proceeds and eventually may turn a pale yellow. Allow the reaction mixture to cool to room temperature after the reflux period.

Name Experiment 5- Post-lab Questions 1. In Reaction B, you observed magnesium metal reacting with a hydrochloric acid solution to produce hydrogen gas and a magnesium chloride solution. Another reaction that has a gaseous product is the reaction of a hydrochloric acid solution (HCl(ag)) with sodium sulfite (Na,so,(ag)) solution to produce a sodium chloride solution (NaCl(aq)) and gaseous sulfur dioxide (S0,(g)). Write a balanced chemical equation for this reaction. 2. The sulfur dioxide produced by aqueous chemistry in the previous...

Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...

Preparation of Triphenylmethanol Using the Grignard Reaction.
RH ROOH CO TO R-R MgBr 1.ether 2.11-SO/10 Icther Grignard reagents are highly reactive and can undergo undesirable RCOH TH₂O side reactions if impurities such as water, carbon dioxide, or oxygen are present. If the organohalogen is added to the R-Mg-X magnesium too quickly, undesired coupling reactions can also occur. In this experiment, you will use 0.015 moles of either benzophenone or ethyl benzoate as the recipient of the phenylmagnesium bromide and this...
