CHM110H5 Lecture Notes - Lecture 2: Ideal Gas Law, Nuclear Chemistry, Stoichiometry
Document Summary
Redox reactions are essential to the field of metallurgy, such as when metal ions are extracted from their ore by acidic solutions through a process called leaching4. In part a of this experiment, the atomic mass of an unknown metallic element was determined based upon the reaction of the unknown metal with aqueous hcl. The reaction of the metal with the h 3o+ ions present in the acid produces hydrogen gas, h2(g), and water. The reaction is as follows: m(s) + n h3o+ m+n + n/2 h2(g) + nh2o. In this work, we used a known weight of metal, acting as the limiting reagent, and hcl(aq) in excess to determine the amount of h2(g) produced. The concept of diffusion is widely used in nuclear chemistry to separate isotopes, such as the separation of u-235 from u-2383. In part b of this experiment, the ratio of diffusion rates of the two gases hcl(g) and nh3(g) was determined.
