Experiment on the reaction of Heating of copper sulphate crystals …
Copper(II) sulfate, also known as copper sulphate, is an inorganic compound with the chemical formula CuSO4. It forms hydrates CuSO4·nH2O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate. Older names for the pentahydrate include blue vitriol, bluestone, vitriol of copper, and Roman vitrio… WebHeat the blue copper(II) sulfate until it has turned white. Move the flame along the length of the test tube from time to time (avoiding the clamp) to prevent water condensing on the cooler regions and then running down on to the hot solid, possibly cracking the test tube. ugee previous year papers book pdf

Web10 feb. 2024 · Part 3: Reversibility of hydration 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. Using a test tube holder, grasp the test tube containing the hydrate and heat over a Bunsen burner flame while holding the test tube at a 45° angle. WebAnswer: If it is the crystals (hydrated), then the water is driven off, the crystals go from blue to white (ish) to anhydrous copper sulphate. The next two steps need extreme heat and reducing conditions. If you heat even further, you get copper oxide (black powder), sulphur oxides (choking poi... WebIts formula is written as CuSO4.5H2O and has blue colour due to water of hydration. It can be converted into anhydrous copper sulphate when heated strongly. When heated, it loses two water molecules at ~63°C followed by two more at ~109°C and the final water molecule at ~200°C and turns to white coloured anhydrous copper sulphate. ugee preparation
