An Investigation Of Hess' Law

Aim: To verify Hess rectitude Research Question: How apprise Hess right be use to find the enthalpy of radical of atomic number 11 hydroxide using the neutralization chemical response between atomic number 11 hydroxide and hydrochloric acid. Theory: Following the justice of conservation of energy, Hesss Law states that the total enthalpy change for a reception is equal to the energy lost or gained by the system. This law remains true no matter what the reception or the steps and ways in which a particular reaction occurs. Theoretically, energy is never lost from a system. It is simply converted to another set of products. In this experiment, NaOH(s) + HCl(aq) NaCl(aq) + H2O(l) [H1] NaOH(s) NaOH(aq) [H2] NaOH(aq) + HCl(aq) NaCl(aq) + H2O [H3] According to Hesss Law [H1] = [H2] + [H3] Therefore [H2] = [H1] - [H3] Variables: Independent Variable: The state of NaOH apply in the thre e experiments. These different states enable the data that pull up stakes be used to verify Hesss law to be collected. Dependent Variable: The enthalpy changes of the three reactions that will bow with different states of NaOH used. Controlled Variables: The room temperature and pressure. The temperature of all the solutions used kept repetitive at room temperature. Apparatus: * 50 cm3 measuring piston chamber (± 0.
