Practical - preparation of crystals of a soluble salt
WebThe mass of the hydrated salt was 2.90 grams so therefore, the percentage by mass of water in the hydrated copper(II) sulfate compound was determined to be 37.2 percent. The class average for the percentage of mass by water was calculated as 36.56 percent. This results in a calculated hydrate formula of copper (II) sulfate pentahydrate, CuSO4 5H2O. Web10 feb. 2024 · Transfer a small amount of solid copper (II) sulfate pentahydrate, CuSO 4 × 5 H 2 O, that just fills the bottom of a clean, dry 150-mm (medium size) test tube.
