Prelab week 1 Calculations Preparation of 1.5μmol/L mixed low-level standard dilution 150μmol/L × V1=1.5μmol/L × 10ml V1=(1.5μmol/L×10ml)/(150μmol/L)=0.1ml Conversion of milliliters to microliters (0.1ml×1000)μL= 100μL Preparation of 3μmol/L mixed low-level standard dilution 150μmol/L × V1=3μmol/L × 10ml V1=(3μmol/L×10ml)/(150μmol/L)=0.2ml Conversion of milliliters to microliters (0.2ml×1000)μL= 200μL Preparation of 3μmol/L mixed low-level standard dilution 150μmol/L × V1=7.5μmol/L × 10ml V1=(7.5μmol/L×10ml)/(150μmol/L)=0.5ml Conversion of milliliters to microliters (0.5ml×1000)μL= 500μL Preparation of the blank samples The volumetric flask will be filled to the mark with 150μmole/L of stock solution to act as blank (reference). Additional two blanks will
Next, about 10 mL of both solutions, Red 40 and Blue 1, were added to a small beaker. The concentration of the stock solution were recorded, 52.1 ppm for Red 40 and 16.6 ppm for Blue 1. Then, using the volumetric pipette, 5 mL of each solution was transferred into a 10 mL volumetric flask, labelled either R1 or B1. Deionized water was added into the flask using a pipette until the solution level reached a line which indicated 10 mL. A cap for the flask was inserted and the flask was invented a few times to completely mix the solution. Then, the volumetric pipette was rinsed with fresh deionized water and

Leah Romero 10/30/2017 Conclusion Lab 3 Chem 102L In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes.
The material for this experiment will be: Control tasting paper (tasteless), 0.003 mg per PTC strip, 0.007 mg per PTC strip, water, small medicine cups for tasting, larger medicine cups for rinsing, tower papers and dark chocolate (72%). This experiment demands 24 students in the Genetics Lab class. Students are going to be asked the level of bitterness in 3 different PTC exponents: 0.003 mg per PTC strip, 0.007 mg per strip and dark chocolate (72%). Levels are from 0-5, (0 being least bitter-5 being extremely bitter).

6 inches of string was pulled out on either side of the pen and we marked the string at the base of the pen with the black marker. Then the pen casing was spun and the timer was started and it was timed how long it took for the 1 washer to make 15 rotations. Then that was repeated 5 times. Then 2 more washers were tied onto the side with 2 washer already for a total of 4. The experiment was repeated 5 times once more.

The solution was warmed to 65oC with constant stirring on the magnetic stirrer till the solid was completely dissolved. Stirring was stopped and 0.4g of charcoal was then added to the solution. After which the solution was transferred to a Buchner funnel with a moist filter paper and the clear filtrate was collected via suction filtration. The residue was washed with warm solution of 10.035g of KI and 15ml of deionized water. 200ml of water was then added to the filtrate in a 500ml beaker with constant stirring.
Most purchased product/service: Bleach • Clorox bleach to be specific, I use it for laundry and household purposes and it is a frequently purchased item of mines.
