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

methods such as muscle DNA extraction usually present samples of high quality but would require harming the organism for extraction‚ similarly blood DNA extraction would be of comparablequality but would be less detrimental than a muscle biopsy. The indirect method (feather) would be difficult to extract DNA as the quality of DNA would be poor however it wouldn’t require harming the species. The difference in quality of the expected DNA extraction would in turn reflect the amount of DNA concentration

Discuss whether indirect taxes on petrol should be reduced Petrol is seen as a de-merit good as it can cause market failure as the free market may fail to take into account the negative externalities of consumption (pollution) because the social cost exceeds the private cost. Consumers too may experience imperfect information about the long term costs to themselves of consuming products deemed to be de-merit goods By imposing indirect tax on producers it raises their costs of production‚ shifting

absorbed or emitted heat or for determining specific heats.” While direct calorimeters measure the amount of heat produced in a small chamber‚ indirect calorimeters measure the amount of heat produced by taking into account the amount of consumption of oxygen and elimination of carbon dioxide. Both contain the same concept‚ but have a different approach. Indirect calorimetry is the preferable way for physiologists to measure the amount of oxygen being consumed and carbon dioxide and nitrogen waste being

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.
