How to make hydrochloric acid?

Answer 1

Warning: This experiment releases toxic hydrogen chloride gas. This experiment must be done in a fumehood or outside. The containers must be glass to withstand the acid. Chemicals: conc. sulfuric acid,sodium chloride,distilled water

Equipment: Round bottomed flask,funnel,test tube,bunsen burner, tripod, gauze mat, stopper with hole in the middle, 3 tubes, 3 1-inch length flexible rubber tubes, stand

METHOD

hold the round bottomed flask with the stand. Pour the sulfuric acid and sodium chloride in the round bottomed flask. Quickly place the stopper in the neck of the flask. Connect the 3 glass tubes and the 3 rubber tubes into a U-shape. connect one end to the stopper and the other in the water. Heat the water with the Bunsen burner and wait about a hour.
