Determining Amount of Zinc to Set Price for Nail Galvanization Introduction. In this experiment the amount of zinc used to galvanize nails was experimentally determined to see if a building supply manufacturing company was charging the appropriate price for the galvanization process. The effectiveness of the experiments was determined by comparing the results of two different methods: gasometric and gravimetric. The gasometric method consisted of measuring the amount of hydrogen gas created when a galvanized nail was reacted with hydrochloric acid, and gravimetric consisted of measuring the mass lost by the nails after the reaction. Analysis of three nails using both methods and using percent difference calculations gave reasonably accurate results which led the price of the galvanization process to increase. Experimental Procedure. Three galvanized nails were weighed to the nearest .0001g, and one nail was dropped into a 6M solution of hydrochloric acid in an Erlenmeyer Flask which was connected to a gas collecting apparatus. The equation for the reaction is: Zn( s ) + 2 H O ( aq ) Zn ( aq ) + 2 H O( l ) + H ( g ) The reaction bubbled, filling the cylinder of the apparatus with gas. When the zinc reaction was completed, the reaction was quenched immediately with tap water. Then the
