Additional Learning Goals for Experiment 4: • To perform titrations and evaluate the reaction between strong and weak acids and bases • To balance and differentiate molecular, complete ionic, and net ionic equations • To relate measured chemical properties to the reactions of chemical species Introduction • Decomposition reaction – chemical reaction in which a single reactant breaks down into two or more products • Double replacement reaction – chemical reaction where two compounds react, and the positive ions (cations) and the negative ions (anions) of the two reactants switch places, forming two new compounds or products We would like to show you a description here but the site won’t allow us. In this lab we explored the rate of a chemical reaction at different temperatures and with. For our experiment, we were investigating the products of a chemical reaction and the items. object flood cv2 In this experiment, we will study the kinetics of the reaction between iodine and acetone in aqueous solution: The rate of this reaction is expected to depend on the concentration of hydrogen ion in the solution, a catalyst, as well as the concentrations of the two reactants.
