Pre-Laboratory Assignment EXPERIMENT #1: PreparationorsolutionsofDesiredStrength Students Name: CIRCLE your lab section: 1) State the Objectives of Experiment #1 PIN: Monday Tuesday Friday Using information from the Manual (pages 16 to 19), explain the three most relevant scientific or technical concepts this Laboratory Experiment supports that 2) 3) Write the required equation (s), followed by explicitly showing caleulation and units: a) Your goal is to prepare 500 mL of a 0.01 M solution of Magnesium Chloride and the substance you have available is the desired Magnesium Chloride Hexahydrate. Calculate the mass that you need to weigh of this substance to prepare solution. Suppose instead that the salt available is Magnesium Chloride, and you proceed to weigh the amount of this substance that you determined in part a). Caleulate the relative percent difference between the two concentrations (a) and b). Explain the significance b) Caleulate the concentration of the solution in b) in units of parts per million (ppm). Explain any assumption, how reasonable is the assumption, and how could you prove that your assumption is correct. c)
d) At normal pressure and temperature hydrogen chloride (HCI) is a gas Commercially available concentrated HCI fe for concentration, the Instructor prepares a first dilution to approximately 1.50 M approximately 0.15 M. Show the volume of 11.0 M HCI that needs to be measured to prepare 1000 mL of a 1.50 M solution and the volume of 1 50 M that students need to measure to prepare 100 mL of a o and students prepare a second dilution to 15 M solution. 4) Provide the name and function of the three pieces of glassware shown in Manual F choose any volume, for glassware Class A. but must report the nominal tolerance for the volume-size you choose, as given in Manual Section l Glassware telerance Function Glassware name and Volume (mL) 5) Use the Safety Data Sheets (SDSs) posted on our Canvas to complete information requested in the table Substance SDS Hazard Most Important ACUTE effects First Aid Measures health Identification risk # Magnesiun Chloride Hexahydrate solid HCL, 1M solution
