utions Procedure: 1. Prepare 50 mL of a 0.100 M solution of LiCl. 2. Using this stock solution, prepare a series of solutions (20 mL each) with the following concentrations: 0.0500 M, 0.0250 M, 0.0125 M, and 0.00625 M. The dilutions should leave-30 mL of the 0.100 M stock solution to finish the series. (Note that each solution in the series is ½ the concentration of the previous solution.) 3. Using the information in the tables below, plot conductivity (mS cm') vs. concentration (mol/L) using Excel (or other plotting software) and apply a linear regression analysis to the plot. 4. Repeat steps 1-3 for formic acid. LICI Formic Acid mS cm 10.66 mol/L 0.10000 ms cm mol/L 1.79 0.10000 7.75 6.30 5.57 0.05000 1,60 0.05000 0.02500 0.01250 1.50 0.02500 1.45 0.01250 5.21 0.00625 1.43 0.00625 Questions: 1. Determine the mass of LICI (42.394 g/mol) required for Step 1. 2. Show your calculations for the volume of 0.100 M LịCI required for each dilution in Step 2. (HINT: dilution law: M,V; = M¿V2) 3. Submit your two clearly labeled plots (including their lincar fits) from Excel (or other plotting software). There is a short video on D2L on how to plot using Excel. 4. Which compound is the stronger electrolyte? What do you believe to be the major factor accounting for the difference?

A student weighs out exactly 1.562 grams of p-aminophenol and exactly 40 mL of water. After dissolving p-aminophenol in HCl, 10 mL of acetic anhydride is added. The student follows the procedure and acetaminophen is prepared. What is the maximum amount of acetaminophen she could obtain from the reaction if the percentage yield is 76%?

What would be your decision in the following case? Justify your opinion.      A refinery is discharging some unknown chemicals into the sea. These chemicals could affect water quality but after decades. The research department is currently working in a solution for this problem. The manager thinks the research team will soon find a solution. He decided to continue with production since all companies are doing the same and the company would lose if they stopped production. What would be your decision in the following case? Justify your opinion

Convert the following pH or pOH values to [H*] or [OH] concentration Example: pH = 7.0, [H*] = 1.0 x 10-7 M pH = 5.3, [H*] = РОН 3 11.1, [Н']]- РОН 3 6.6, [ОН]- pH = 2.5, [OH]] = In two or three sentences, compare and contrast the Bronsted-Lowry definition of acids/bases and the Arrhenius definition.
