Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister
