The sample was hydrolyzed by 2 ml sulfuric acid 1 M at 80 oC for 24 h. The hydrolyzed samples were diluted‚ neutralized and filtered through a 0.22 μm filter. Finally‚ they injected to HPLC system. Operation conditions were as follows: HRC-NH2 column (diameter: 4.6 mm i.d.‚ 15 cm‚ shimadzu‚ Japan); flow rate‚ 1.0 mL min-1; temperature‚ 40 oC; injection volume: 10 μL; mobile phase‚ acetonitrile/water (75:25).

of solution * The molar heat of solution of a substance is the heat absorbed when one mole of the substance dissolves in a large excess of water. It is expressed in kJ/mol. * The specific heat of water is a constant‚ with a value of 4.18 J/ g*oC. AIM: To determine the molar heat of solution for two different solids Equipment: * A calorimeter (made using 2 Styrofoam cups with a cardboard lid) * Electronic balance * Measuring cylinder * Thermometer * Ammonium nitrate (NH4NO3)
