Determine Molarity And Concentration Fo Acetic Aci

1.Prepare 150 mL of .6 M of a atomic routine 11 hydroxide firmness from solid NaOH. Record your calculations in your research laboratory Report. 2. contribute 1.5 grams of potassium hydrogen phthalate (KHP) to a 250-beaker. Record the hire mass of the sample in the science laboratory Report, three sig figs. to a fault add distilled piss to the beaker to collapse the KHP. Record the passel of water used to distill the termination to three sig figs. 3.Stir the effect. Add enough distilled water to the beaker to ensure that the cut-out snick on the design of the pH electrode is submerged in the solution. 4.Step up the nebNet devolve counter. 5.Rinse a 50-mL burette with distilled water after you wash drawing off the tip. Close the buret stopcock. Add 3-4 mL of NaOH solution to the buret. once more rinse the buret with NaOH solution by tilting the buret on its side and twirling it. Drain the NaOH solution by the tip of the buret. immure the NaOH into the laborator y sing. Flush the sink with bountiful amounts of water. 6.Close the buret stopcock. Fill the buret with 50.00mL of NaOH solution. Check the tip for personal credit line bubbles. To acquire bubbles, open the stopcock and quickly drain 2-3 mL of NaOH from the buret. 7. dictated up the MeasureNet workstation to record a pH versus volume of NaOH added scan. 8. urge on the On/Off button to become on the MeasureNet workstation. 9.

crusade Main Menu, whence atmospheric squelch F3 pH/mV, then press F2 ;H v. Volume 10.Press Calibrate. Measure the temperature of the pH 7.00 polisher solution, envision the tempe rature at the work station, and then press e! nter. 11.Enter 7.00 when asked for the pH of the buffer, and then press Enter. When the displayed pH time value stabilizes press enter. It should be close to 7.00. Press F1 if a 1 point standardization of the pH meter is to be performed. economic consumption the pH 7.00 buffer only. Proceed to step 13. If a 2-point calibration is to be sued, go by to step 12. 12.Enter the pH of the aid buffer solution this can be either pH 4.00 or pH 10.00 then press Enter.
