Organic Lab Trial 1 Trial 2 Trial 3 Observations We added the 30ml of warm water with 4.7 grams of borax powder in to the cup labeled ‘Borax Solution’ and also added a few dots of green food coloring. We then stirred it until all the solutions were completely mixed. When this happened the borax and water turned into a watery green solution. then we added 15ml of glue in the cup labeled ‘Ball mixture’ and added the mixture we made

In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to

In the second separation of this experiment‚ the Erlenmeyer flask with the first filtrate was put into a beaker so the filtrate was in the beaker. The beaker was then heated on a hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in

balance‚ and the exact mass was recorded. The hair was then transferred to a 50cm3 conical flask‚ to which 10ml of concentrated nitric acid (69-72%) was added. The solution was then stirred and heated on a hot plate‚ for about 1 hour‚ until the hair has dissolved‚ and a dark brown solution was obtained. The solution was then left to cool‚ and then was filtered using a fluted filter paper‚ into a 50ml volumetric flask. The filtrate was then made up to the 50 ml mark‚ using deionised water.

is used as a sample to study the growth kinetic of microorganism in shake flask. A different volume of E.coli was transferred into 250ml Erlenmeyer/shake flask containing media for the nutrient of microorganism. The different volume of microorganism transferred will give the different effect of reading on the constant volume of media used. There are three ways to test the growth kinetic rate of microorganism on shake flask‚ which are by optical density (OD)‚ glucose analysis and cell dry weight (CDW)

The Octopus Flask is noted as one of the most popular recorded painting that dates back to 1500-1450 BCE. The art piece is a painting on a ceramic vessel‚ what people referred to as “bottle”‚ it came from the east Cretan site of Palaikastro and is now displayed at the Archeological Museum at Iraklion‚ Crete. The Octopus Flask‚ or the “bottle”‚ is decorated with paintings of marine life in celebration of the Cretan Maritime Power. It consists of an octopus and other marine life “floating” in its

The vigorous intimacy had left us quite weary and I led him into the parlor room. I placed myself upon the burgundy velvet couch and took a fresh Italian cigar from my cabinet while he sat on the chair across the dimly lighted room. He stared at me with a heavily lidded lustful gaze as he took a sip of his glass of Amontillado

OBJECTIVES The objective of the experiment was To calibrate a 10 mL volumetric pipette To calibrate a 25 mL volumetric pipette To calibrate a 100 mL volumetric flask To calibrate a 50 mL measuring cylinder INTRODUCTION The purpose of this experiment is to study the relationship of several types of volumetric glassware and the accuracy of measuring the volumes of liquids very precisely in quantitative laboratory work. The accuracy of the measurement the volumes is the degree of closeness
