    Lillian Zhang AP Chemistry 3rd Period Formula of an Unknown Hydrate The purpose of the Formula of an Unknown Hydrate lab is to determine the weight percentage of H2O hydrated to an unknown salt and the empirical formula for the hydrated salt. To do this‚ a massed amount of the hydrate is heated over either a hot plate or Bunsen burner. This causes the water to be removed‚ leaving the anhydrous salt behind in the dish. The mass of the anhydrous salt‚ now with the absence of water‚ is less than

    Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
