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

Lab: STOICHIOMETRY The reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power

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

Calculation on the molar enthalpy change of a neutralization reaction Principle H2SO4(aq)+2NaOH(aq)=Na2SO4(aq)+2H2O(l) The reaction is a exothermic reaction‚ when the heat released by it is absorbed by water‚ the temperature of the water increases. The heat produced by the reaction can be calculated if it is assumed that all the heat is absorbed by the water. Heat change of reaction=-heat change of water =-mH2O×cH2O×△TH2O As the water has gained the heat produced by the reaction‚ the heat change
