CHM110H5 Lecture Notes - Lecture 1: Acid Strength, Sodium Hydroxide, List Of Lakes By Volume
Document Summary
The purpose of this experiment is to determine the heat of ionization of a weak acid. This was done by mixing a strong acid with a strong base and a weak acid with a weak base and noting the temperature change between fifteen second intervals. o. Figure1: this figure represents the temperature change for water. Table 1: tabluated values of hot and cold water. |heat lost by hot water| + |heat lost by calorimeter| = | heat absorbed by cold water| H20 t)| + |(cp cal t)| = |(vc cp. = |(50. 0ml)(1. 00 gml-1 )(4. 18 jgk-1)(9. 95k)| cal 8. 95 k) = 2079. 55 j 1870. 55 j. Figure 2: this represents the temperature change of a strong acid. Table 2: tabulated values of strong acid and base. Looking at the calculations of moles, there was an excess amount of acid that reacted in the experiment. Heat released by reaction = heat gained by surroundings.
