. Three students are asked to discuss the percent error obtained in this lab.
Select the student that employs correct scientific reasoning.
Student 1: The percent error could be caused by mixing the reaction too quickly, the friction
caused by mixing would increase the change in heat measured.
• Student 2: The percent error could be caused by the salt not completely dissolving, therefore the
change in heat per mole would be accidentally low.
. Student 3: The percent error could be caused by the change in pH of the solution, this would
decrease the change in heat accidentally.
