Potassium dichromate and hydrochloric acid
WebAnswer: Potassium dichromate is a strong oxidizing agent, strong enough to oxidize HCl to Cl2 (chlorine gas—I hope you did this experiment in a fume hood). In this reaction, … Web2-methylpropan-2-ol and hydrochloric acid, sodium hydrogencarbonate is used to remove any unreacted HCl. Why isn’t a strong base used? A stronger base (such as NaOH) would react with the halogenoalkane product. Hydrolysis of this product would cause the alcohol to be reformed. https//bit.ly/pmt-cc https//bit.ly/pmt-cc https//bit.ly/pmt-edu
