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.

amounts of water consumed in the brewing process as well as washing and sterilizing procedures. It is estimated that between 4 and 7 L of water is required to produce 1 L of beer. Beer is the fifth more popular drink in the world so to meet this demand; large quantities of water are required. Water chemistry has an effect on the brewing efficiency as well as the taste‚ so water from water authorities must be treated in order to produce water which is acceptable for brewing. Demand for water has become

Pond Water Paper DIRECTIONS STYLE TENSE: In all sections of the paper‚ present tense should be used to report background that is already established. For example‚ "The cell membrane is the barrier which separates the inside of the cell from the outside." Use future tense for work that you will do. For example‚ "This experiment will test the hypothesis that some anti-microbial agents can permeate the cell membrane during division to inhibit growth." Use past tense to describe the methods (what

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

SEX DETERMINATION IN FORENSIC ODONTOLOGY Identification of living beings and dead bodies is of great importance in Forensic science. Sex determination is one of the important steps in establishing identity. Sex identification in international sports: In 1932 Helen Stephens and Stella Walsh: Hitler’s Olympics In 1936 Stella accused Stephens of being male and so a crude physical examination including gross physical examination of external genitalia was done. In 1966 gender identification became
