Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

molecules that are in the hydrate. Copper(II) sulfate pentahydrate‚ or CuSO4 * 5H2O‚ is a ratio of one copper sulfate to five (penta) molecules of water. Copper sulfate pentahydrate is a blue hydrate while anhydrous copper sulfate (CuSO4) is white. To get anhydrous copper sulfate‚ copper sulfate pentahydrate must go through an endothermic reaction and have all of its water molecules evaporated. It then becomes the white‚ flaky‚ and chalky material anhydrous copper sulfate. Adding

15.2 Born-Haber Cycle Our calculations of enthalpies so far have involved covalent substances. Now we need to look at the enthalpy changes involved in the formation of giant ionic lattices. Lattice enthalpy is defined as either the: ’the enthalpy change that occurs when one mole of a solid ionic crystal is broken into its ions in the gaseous state‚ at standard temperature and pressure. Because all the bonds in the ionic lattice are broken‚ it is an endothermic process‚ ∆H is positive. ’ The
