For this lab, we are trying to find the heat capacity when we neutralize acids and bases and seeing how much energy is produced from the reactions. Experiment 4 Heat of Neutralization Purpose: To calculate enthalpy change of a reaction by using calorimeter and understand the difference between endothermic and exothermic reactions. This heat is generally indicated in Joules for the reaction as written. This video is created by http://www.course.onlinetuition.com.my/More videos and free notes are available at http://spmchemistry.blog.onlinetuition.com.my/ This is an IOT lab, where you will be asked to design the experiment and your TA will perform it while streaming data in real time to a Google Sheet. The heat of neutralization that is lost in the chemical reaction (the system) is gained by the calorimeter and its contents (the surroundings). Eq. In chemistry what ... Heat of Neutralization: Calculations Name _____ 5. Why? Protocol (neutralization experiment): Make the baking soda rocks 1. You will also measure the heat of dissolution of NaOH. 2 0 obj 1 0 obj The purpose of this experiment is to determine the heat of reaction for a neutralization reaction. �v7I�6_\������]lyc�I�V�6}��R�(������L���|�惺��U�j��؋WU5_��K��b�}��b��C~�i~W��ؖ����� ��=}r�,�4���>�,��8KD���!���;��ǧO��'���OO����H�Y��*j/��|��A1��(�ï|2��r�6���s-�U�R@FD����-�I���*�*�4�Ԩ���B��r3���A������ {�M��i�o=�A^�c��`���0v� ����K]���w,����G��q�PF�N�a�!�}��:I����� 4 0 obj endobj �� Enthalpy of Neutralization Jonniel S.

Therefore, heat capacity of calorimeter is equal to heat gained by the calorimeter / temperature increases and the answer is 33 J/°C. �O�塝�.�GM�x�G˜q$.���~��E�ZZ*������ڷ����5�4� ?-��1��}�3��л��#H� W�s��ك����Vs���vW�\Xet��S��m�mt|r��=��s��tIt��xw�d!Dwً(R"���R�c$/�)J/����2�4��x���J�rPX�_G�����aq}9M��MA�q� "�8Ls�c�X�D�Ǒ�F����.o���€F��QR�O��� йǺ-��JR�@����x�T$ �è�`�b�ɉٍ��A�|��9� �k��O�l���\g!� In this experiment, after finding the heat capacity of the calorimeter, we'll neutralize two acids and calculate the heat of neutralization. 4. <> Using that information, and your data, calculate the energy change in the surroundings (q surroundings), in each of your experiments. The heat given off by the neutralization reaction, ∆H, is the sum of the heat absorbed by the solution and calorimeter. So the heat generated by the reaction equals the heat gained by the contents of the calorimeter, but the q values have <> %PDF-1.5 2.
