4.0 DISCUSSION The biological method of quantum dot synthesis using F. oxysporum has been proven to successfully synthesize highly photostable and luminescent QDs in an environmentally friendly manner. However, in order to increase the demand for biological methods of production, the yield of QDs synthesized by this method must be increased. This study considers several factors that affect QD synthesis by fungi and modifies them in F. oxysporum in order to increase QD yield. The fungus, F. oxysporum

Molar Mass of a Volatile Liquid 2.Objective- We receive a unknown volatile liquid and try to find it's molar mass.In order to do this we must know how to convert units of measurements and the formula required. 3.Introduction- In order to do this experiment you must know certain terms and formulas. Molar mass is defined as one mole of this substance. The molar mass is what we are trying to find.One equation use d to find molar mass is MW=m/n. Another thing needed to know is the Ideal Gas Law. The

An Ocean Optics 2000 and four cuvettes, containing .1M solutions of the following: Ni(NO₃)₂ , Co(NO₃)₂ , K2CrO4 , and Cu(NO3)2 , were gathered. Each sample was placed in the OceanOptics, and the colors that were absorbed were recorded, and the colors that were transmitted were recorded. Also, the maximum absorbance and maximum transmittance (%), recognizable as the peaks of the absorbance and transmission graphs, respectively, were determined, and the corresponding wavelengths were recorded. A solution

In this experiment, a calibration curve and standard addition was used to determine the concentrations of fluoride in mouthwash and tap water. Bottled water was also analyzed by the calibration curve, but the results were flawed as the concentration of fluoride did not fall in the range of the calibration curve. Mouthwash was first analyzed by a calibration curve, which was determined to have a fluoride concentration + standard deviation of 194.5 + 34.9 ppm. Analyzing mouthwash with standard addition

1. Explain how an acid and a base are distinguished and how the pH scale operates as a logarithmic function. An acid and base are distinguished by the negative hydrogen concentration in a substance. If a substances loses its hydrogen concentration, it is more acidic. If a substance accepts more hydrogen, it is considered a base. The pH scale operates as a logarithmic function because the value changed 10x or greater. A pH of 3 is 10x more acidic than a substance with a pH of 4. 2. Explain what

Field sobriety test: Review of Top 3 Sobriety Tests No. 2 Brief description of the stop The motorist in the video Top 3 Sobriety Tests No. 2 aroused the officer's suspicion when her car was veering between lanes the highway. When stopped, the motorist seemed uncertain of what she was doing and where she was. "I don't know," she replied when asked how much she had to drink. She was barely able to put the car in park and seemed more concerned about tying her shoelaces than the test or her serious

The research question for the Alka Seltzer Lab is, “What is the effect of different surface areas of an Alka Seltzer tablets reaction time?’. Inside of an Alka Seltzer tablet there are two key ingredients; which are citric acid and baking soda. When a tablet is dropped into a liquid, the acid and baking soda show a physical reaction of fizzing and eventually dissolving. Materials needed for this lab was goggles, aprons, beakers, water of the same temperature, mortar pestle, and three alka seltzer

In this experiment we will be titrating the titrant sodium hydroxide against the analyte, which is the substance being analyzed, hydrochloric acid. Titration is the process of analyzing base and acid added together. The objective is to calculate the unknown concentration of hydrochloric acid with the standardized solution of solid sodium hydroxide. The standardized solution is the known concentration but since sodium hydroxide naturally reacts with air, we must first determine the true concentration

You prepare a standard solution by using the M1V1=M2V2 formula, and putting the information to solve the equation. An indicator is going to have a reaction with hydroxide ions or hydrogen ions to determine whether the substance is a base or acid. The role of an indicator in a titration is to determine how many oxygen or hydroxide ions are in a solution. The laboratory method that is used to titrate an unknown strong acid solution is a titration. When you drop NaOH ions the OH ions
