9/25/13 Endothermic Reaction Lab Report The Effect Ammonium Nitrate has on the Temperature of Water During this lab students are going to mix water and ammonium nitrate one gram at a time and observe the change in temperature that is occurring. The students are then going to record the data on a table and later will be able to make a graph of the results. A hypothesis for this lab could be if ammonium nitrate is added to water then the water temperature will decrease. . Hypothesis: If

of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get
