Gold penny home lab activity #10. introduction. the “gold penny experiment” is a popular demo experiment in which a copper u.s. penny is “converted” to gold. the demonstration involves heating a penny immersed in a solution of powdered zinc and sodium hydroxide. after a few minutes, a coating of zn occurs on the surface of the penny.
How To Make Gold Pennies Science Experiment Science Experiments How to make the silver pennies turn gold. grasp a silver penny with tongs. gently heat the penny in the outer (cool) part of a burner flame or with a lighter or candle (or even set it on a hotplate). remove the penny from heat as soon as it changes color. rinse the gold penny under water to cool it. Below is the entire lesson plan for the lab experiment that i use with my students to perform the "gold penny lab". we have a friendly classroom competition with this lab to see who can make the most convincing gold penny and the winners, as determined by student votes, are inducted into the "79 club" (because the atomic number for gold is 79) and are dubbed "master alchemists". Alloys: the copper, and penny experiment november 28th, 2017 objective: the goal for this experiment is to determine the percentage of copper and zinc in an old and new penny with an fluorescence (xrf) spectrometer. alloys are homogeneous mixtures of two or more metals that combined together metallic bonds. After a penny is completely coated in zinc it can be removed and washed to remove any sodium hydroxide solution. at this point it's ready for the bunsen burner. in order to turn the penny "gold" we'll melt the thin layer of zinc on the outside of the penny into the copper underneath. when we do this we'll make the alloy brass which has a nice.

Experiment: 1) take a penny and drop it into the boiling sodium hydroxide and zinc mixture. let it sit for about two minutes. 2) pull the penny out of the water with a pair of crucible tongs and let it cool and dry on a paper towel. do not touch the penny with your bare hands! record the appearance of the penny here:. Blot dry with a paper towel. step 6 making an alloy: using the tweezers, one penny at a time, hold the penny at its edge and place it in the flame flipping the penny over so both sides are heated equally. after approximately 4 seconds remove penny from flame and cool with water. your penny should appear gold in color.
