Q Part A. Observations: Measuring Temperature Changes when Salts Dissolve in Water Each bench of 8 students will be one team and collect data for four salts. Every pair of students will investigate one salt. The data will be shared with the team. The salts to be investigated are the two ammonium salts, and any two of the other salts. Assign one salt to each pair of students. Create a table that has rows for each of the four salts, with a column each salt dissolution reaction, the initial temperature, the final temperature, the change in temperature, ?Hº, and assignment of the dissolution process as exothermic or endothermic.
