Detection of Ions in Solutions Using Acid/Base Chemistry: A Quality Control Test Objective: This lab focuses on the detection of ions using titration as an analysis tool. You will standardize NaOH and HCl solutions so that you know the exact concentration and then prepare samples of common household items in order to determine the amount of calcium in Tang®‚ Mg(OH)2 in Milk of Magnesia‚ etc. You will learn to prepare samples of a specified concentration‚ learn about acids and bases through

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

The halides in unknown solution were identified as iodide and chloride based on their experimental E°(Ag/AgX) values‚ -0.16 ±0.01V and 0.22 ±0.02V respectively. These results were both accurate with percent error of 5.96% for iodine and 0.9% for chloride. The literature value of E°(Ag/AgI) and E°(Ag/AgCl) were -0.151V and 0.222V respectively (1). In addition‚ the literature vales lay within the 95% confidence interval for both halides therefore the results were accurate. These results were precise

The lab today was focused on finding the ratio of reactants to products to be either 1 to 1 or 1 to 2. In our case the reactants was Lead (II) Nitrate and Potassium Iodine. These two when mixed together make Lead Iodide and Potassium Nitrate. We also had to try and find if the number of moles of Lead(II) Nitrate was the same as the final number of moles for Lead Iodine after the experiment. Our data for the lab had pinpoint accuracy.
