Experiments
1. Burn Mg metal.
2. Electrolysis of H2O -> H2 + O2
3. Different color flames (NaCl, )
4. Extract Bismuth Metal from Pepto-Bismol Tablets.
30g pepto-bismo (bismuth subsalicylate) + 260 ml 32% HCl in 1.3 L H2O -> salicylic acid + bismuth chloride -> filter -> bismuth chloride + Al foil -> bismuth (black powder) -> heat in inert atmosphere -> Bi metal
5. Li metal from Li battery -> burn.
6. DNA from strawberries
7. pennies + HCl -> Zn dissolves, laving shell of Cu
