ISE: The Determination of Chloride Unknown: #34 I. Purpose: In experiment V‚ “ISE: The Determination of Chloride”‚ the concentration of an Unknown Chloride solution‚ and the Wt% of NaCl in a sample of celery salt‚ were both determined. To determine the concentration of an Unknown Chloride solution‚ a Calibration plot is first prepared. The Calibration plot is made by first measuring a series of known concentrations of Cl- (with the same activity of the unknown solution) and obtaining

Experiment A Spectroscopic determination of Iron with Phenanthroline Unknown # 2 Mass of Mohr’s Salt: 0.2040 1. 5mL of 6M acetic acid was measured and transferred into a 100mL volumetric flask with a pipette and diluted to the mark. Concentration = [0.2040(±0.0001)g/100(±0.08)mL]*[(1mol/392.16g)/(1L/1000mL)] = 0.005202(±0.09382%) = 0.005202(±0.000005)mol/L 2. 10mL of the above stock solution was transferred to a 250 mL volumetric flask and diluted to the mark.

Eric Wu 117 Experiment 1.6: Determination of Density Abstract: The purpose of the experiment was to determine if density is an intensive or extensive property of matter. The experiment proves that density is an intensive property. The density of an object remains the same no matter how much of it is present. The density is an intensive property because mass and volume changes at the same rate. Introduction: This experiment was designed to determine if density is an intensive or extensive
