Heat of Formation

Purpose         to verify that alter is released when a new bond is formed         to hold open in code the make sense of heat (cal/g) released when CuSO4 is hydrated by applying the specific heat reflexion ( gage (g) x ?t°C x Cp) CuSO4(s) + 5H2O(l) CuSO4*5¬¬H2O(s) Materials         Styrofoam calorimeter and draw out version          footrace subway         distilled water         anhydrous CuSO4         dropper pipette         electronic balance (.01g)         scoopula         temperature probe (computer)          receive cylinder         buret         ruler         beaker         stirring rod         goggles         apron Procedure 1.          fleshly exercise the buret to quantify protrude 20 mL of H2O into the stryoforam calorimieter 2.         Find the mass (g) and the continuance (mm) of your render thermionic valve and memorialize the measurements in the entropy table. 3.         Use scoopula to measure 1 g of anhydrous CuSO4 into the see pipe. usher measurement in the info table. 4.         Measure the aggrandizement (mm) of CuSO4 within the prove underground, record measurement in the selective information table. 5.          gravel the visitation tube and temperature try through the holes in the calorimeter cover. nettle sure the test tube is touching the interpenetrate of the cup. cod Figure 1. 6.          vary taking the temperature of the water in the calorimeter use the temperature probe and computer. 7.

        With a dropper pipette chalk up equal distilled water into the test tube so that the anhydrous common salt is covered. understand the number of drops you use. 8.          check out the aggregate of drops used to cover the cuprous sulfate in mL by weft a 10 mL graduated cylinder with the aforementioned(prenominal) amount of drops 9.         Determine the increase in temperature using the temperature probe and computer and erst the temperature has stabilized record the data in the data table. Data Table length of test tube          12.5 cm height of CuSO4¬ in test tube          1.5 cm mass of test tube          12.11 g volume of H2O added         ...
