-1Chemistry 101 Lab Report - Experiment 3 Reactions in Aqueous Solutions - Salinity Measurements Introduction: Experiment 3 was over reactions that occur in aqueous solutions. Specifically, we used the San Antonio Bay and estuaries fed by the Guadalupe River to address the chloride ion concentration of the water. The Mohr (Argentometric) Titration method was used to precipitate this specific titration. A color change, indicating the end point of the titration, occurs when silver chromate precipitate is formed. We addressed the chloride ion concentration and how to properly sample the water system to model it.

Results: Concentration of AgNO 3 (M) 0.01315 Average Molarity 0.01308 Trial Cl- Concentration / M 1 0.00132 2 0.00133 3 0.00132 Calculations: Discussion: Experiment 3 was over conducting Mohrs (Argentometric) titration. We titrated a blank first and then we standardized a silver nitration solution. Finally, we analyzed samples of water from San Antonio Bay. Conclusion: The average AgNO 3 concentration was 0.01308....
