Experiment 1lab report

Pure water has a water potential of 1 atmosphere. Then we discarded the used glucose test strip. Hence, the study of acceleration can be done without the inaccuracies that friction brings.

In relation to both the classification reagents, one possible impurity that could cause false positives would be trace amounts of any starting material left over, namely the Hydrobromic acid in the case of the n-butyl bromide or the Hydrochloric acid in the case of the tert- butyl chloride synthesis.

The two by products mentioned above are also removed by the concentrated Sulfuric acid along with any unreacted alcohol.

The observations tell exactly what happened when you did the lab. In MLA stylethe components are arranged this way: The first trial represented a medium magnitude movement.

Extra vigilance was taken this time around so as to get the optimum yield of the final product and so as to not have a repeat of the same during the procedure for the synthesis of n-Butyl Bromide. At this point, the product layer will turn milky. Having sterilized conditions allows for conclusions about life from inorganic matter, instead of life introduced into the flasks from the environment.

Another SN2 reaction leading to the formation of n-Dibutyl ether is possible if the alcohol itself will act as a nucleophile: While looking at each individual seismograph, the greatest magnitude was observed and identified.

This was achieved during the reflux portion of the experiment: So the main explanation could be that the gaseous n-Butyl Bromide, instead of condensing at the condenser, escaped out because there was no more water running, which also explained the smell that the group noticed prior to discovering the error.

Since the distilling flask had been covered with foil to aid in the rise in temperature, the group had also failed to notice that the contents had already run out through the course of the distillation.

First off we have the reaction between the starting materials Sodium Bromide and Sulfuric acid to form Hydrobromic acid, which will be used in a later step to form our end product: Purposes can be stated as a question. Dissolve an amount of sodium bromide solid, corrosive in 3.

The procedure you use affects the results. What products would you predict if isopropyl alcohol rather than n-butyl alcohol had been the starting material in this experiment. Swirl the contents constantly for 5 minutes without the stopper to allow any gases from the reaction to escape.

In context, the reaction is not supposed to happen, for one because the substrate is of a primary structure, meaning that it undergoes the SN2 mechanism. Weigh and then do necessary calculations for yield. The calculations section should have example calculations of the following: It is prudent to be vigilant in these series of steps and label all layers drawn off and testing them to see if they actually are the aqueous layers that can be discarded.

Add 1mL of concentrated sulfuric acid, and mix the contents well. Remove the n-butyl bromide from above, with a plastic pipette, and place it in another dry small test tube. What molecules pass through the cell membrane easier than others.

The bread stayed the same size. So the main explanation could be that the gaseous n-Butyl Bromide, instead of condensing at the condenser, escaped out because there was no more water running, which also explained the smell that the group noticed prior to discovering the error.

Remove the n-butyl bromide from above, with a plastic pipette, and place it in another dry small test tube. Note that drawings are not drawn to accuracy and are meant only as basic illustration: At this point, there are two reactions to take note of.

Repeat with 30mL of saturated sodium chloride solution, which will help in the purification process, so you get as much of the end product as possible by pushing any of the stray organic material back into the organic layer.

Exp: Gas Stoichiometry

More in depth discussion on their explicit definition and their underlying concepts will be included through the course of this laboratory report. Experiment 1 — Properties of Organic Compounds _____ Pre-lab preparation In your notebook, (1) In one or two sentences, state the purpose of this experiment.

(2) Draw skeletal structures of all the organic compounds you will be working with in this lab. Include lone pairs and formal charges, if any. A reasonable place to find structures. 40 Lab Report Templates & Format Examples Lab report templates are documents which are written to explain, describe and analyze a laboratory experiment which investigates a scientific concept.

Usually, they are assigned to students to be able to. [Reference 1] Lab Report was written according to the guidelines of the rubric II: Purpose of the Experiment: In this experiment, we aim to observe the biology of sexual reproduction and the ideas of Mendelian inheritance by observing and analyzing the life cycle of the C-Fern.

To do this we are.
