Analysis of a Commercial Bleach Lab Guidelines • Name, Exp. Name, Number, Date (we did lab), Partner(s) • Purpose • Compound Names, Formulas, and Molar Masses (5 used – no formula or molar mass for starch) • Reactions (use the four listed on the front page of the lab) • Procedure/Observations • Include initial observations and final observations/odors, masses of KI… • Results (Data Table) • Make a table that has your data of KI masses, and the three volumes (from the three trials) needed to titrate the bleach • Calculations (Data and Calculations Section in lab) 1. Use the equations given on the front page to determine the number of moles of sodium thiosulfate that are equivalent to one mole of sodium hypochlorite. 2. From your three trials, calculate the average volume of Na2S2O3 needed for the titration of 25.00mL of diluted bleach.
Approximately how much calcium would you ingest by drinking eight 8-oz glasses of your local water? Hint: 1 oz (fluid ounce) = 29.57 ml. Answer: 8 oz x 29.57 ml/oz = 236.6 ml per 8-oz glass 236.6 ml is equal to 0.2366 L (in one 8-oz glass) 0.2366 L x 0.00033 mol/L = 0.00007808 moles of Calcium 0.00007808 moles x 40.078 molar mass of Ca = 0.003129 grams 0.003129 grams of Ca = 3.129 mg of Calcium per 8-oz
Part D: Density of Methanol 1) Find the mass of an empty 10 mL graduated cylinder, and then fill approximately 9 mL of methanol and record volume. 2) Find the mass of the cylinder and methanol, subtracting the initial mass from the new mass to determine the mass of methanol. 3) Determine the density and percent error. Data: Part A: Density of a Rectangular Solid/Cube Block # 9 (cube – brass) 1. Mass – 132.32g 2.
