IB Chemistry Experiment 4 Composition of a Post-1983 Penny Lab Report Background: Through the use of percent composition one can easily find out how much of a certain element is in a compound or an item such as a post-1983 penny. The experiment will be using HCl a strong acid to dissolve all the zinc inside the outer copper shell. The reaction follows as such; Zn+2HCLZnCl2+H2‚ but there will be no reaction with copper. The portion that will be measured is the mass of copper left after all of
