Calorimetry and hesss law I can arrive to target reaction itâs a lab report
We can use this to solve for the heat capacity of our calorimeter, C, by using AT: qcalorimeter = C à (Tf-T) °C The heat capacity of the calorimeter will probably be a rather small number but it should be positive. If a negative value for the heat capacity is obtained, then C should be adjusted to zero, In this Lab In Part A of the experiment, for the acid-base neutralization reaction is calculated. H'(aq) + OH-(aq) â H20ã® dHncu" ? The heat produced in the neutralization reaction is absorbed by the calorimeter and the solution, composed of HCI and NaOH. Since the solution was created by mixing HCI and NaOH, the quoln Can be broken down, to give: We will assume the specific heats of NaOH and HCI solutions are the same as water, 4. 18 J/(g à °C). The mass of the HCI solution is collected in step 3, The mass of the NaOH solution is calculated from the volume used in step 6 and the density 1.083 g/mL. T and T, for solutions are both taken from the graph (for details, see graph analysis) and To is the original measured temperature of the NaOH solution, step 4: qHC1-4, 18 J/(g à "O à mass of HCl solution in g à (Tf-T) °C Qwaon® 4. 18 JOg à °C) à mass of NaOH solution in g à (Tr_TJ °C qcalonmeter-c à (T-T) °C
