NaOH Concentration (M): 0.09669M Trial 1: Inital Volume of NaOH: 0.55mL Final Volume of NaOH: 28.25 mL Trail 2: Intial Volume of NaOH: 18.1 mL Final Volume of NaOH: 46.1 mL Concentration of HCl Solution Subtract the initial buret reading from the end point reading. Convert the readings to liters by dividing by 1000. Solve this equation for the concentration of HCl: (CHCl) (0.01000 liters ) = (CNaOH) (volume of NaOH in liters). CNaOH is the normality of the NaOH you recorded from the bottle. Average the two HCl concentrations.
Solid calcium carbonate, CaCO3, was added to a solution of pure water. Analysis found 1.20*10-3 M Ca2+ ions in solution. Calculate the Ksp of CaCO3. Be sure to use 3 significant digits in your answer.
3. What units are used for dissolved oxygen in this experiment? What do they mean? The units are ppm (parts per million); meaning, the number of milligrams of molecular oxygen in every million milliliters of solution. The units are mg/ml; meaning, the number of milligrams of molecular oxygen in every million milliliters of solution. The units are mg/L; meaning, the number of milligrams of molecular oxygen in every liter of solution. The units are mg/L; meaning, the number of milligrams of water in every liter of molecular oxygen.
