Distinction Level BTEC Applied Science Assignment A - Titration Practical - Making a standard solution (Verified) Why is it important to calibrate equipment Making sure that your equipment is calibrated is a crucial step in assuring the accuracy of your data. If you use equipment that read the wrong quantity, they'll be useless. If this step is skipped, it might lead to working with too much or too little of a substance, which can be problematic in some situations. To ensure that our result...

CHEM 104 Experiment 1 Kinetics Summer 2023 Portage learning/Title: Kinetics Purpose: The purpose of the first reaction was to vary the concentrations to observe the relationship of concentration and rate of the reaction. The purpose of the second experiment was also to vary the concentrations of hydrogen peroxide and iodine and determine how the rate was affected based on the concentrations. Order of reaction was also discussed and determined in the first and second reactions. The purpose o...
