Webthiosulfate solution, and adjustment of the copper sulfate solution (Fehling’s A solution) concentration to provide blank titers in this range is recommended. 2. Copper oxidation of carbohydrates is not a simple reaction; end products are mixtures of acids, so equations are not usually written. Consequently, Webcopper and 5% zinc. These copper rich pennies are currently worth more as a metal source than their face value. • Pennies minted after 1982 to the present day are only made up of 2.5% copper. This copper is plated onto a zinc core that makes up 97.5% of the penny. • The determination of copper in both pennies made
