modern (post-1982) penny by using a strong acid to react and dissolve the zinc core‚ leaving only the copper coating. Once only copper remains‚ we will compare its mass to the entire mass of the penny to determine how much of a penny is copper and how much is zinc. Titration Experiment Day 1: 1. Obtain one 50.0 mL beaker‚ and label the beaker with your NAME and HOUR. 2. Obtain a penny dated 1982 or later. Wash the penny with soap and water to get it clean. 3. Using a triangular file to make
