of the samples may have been contaminated by previous groups if the same pipette is used between thedifferent fluids. In the mixing process, the errors associated are related to the magnetic stirrer not being cleaned or rinsed after and between mixtures. Also, when removing the stirrer, a small amount of liquid is displaced which could influence the final measurement. Lastly, the errors from measuring volume and temperature are similar to the initial errors in the measuring components step. For temperature specifically, the error resides in the placement of the thermometer and if it touches anything other than the solution.5. Results1.
