Experiment: Density of Liquids
Analysis Questions

Directions: Answer in complete sentences.

In your lab notebook, histogram the class data for the densities of Liquid A and Liquid B.
Differentiate the boxes for each liquid with different colors or shading, and indicate this with a Key.
For your horizontal axis, please use an interval width of 0.02 g/cm³ and count by odd numbers (i.e., 0.67, 0.69, 0.71, etc.).
Don’t forget to give your graph a title, and label both of your axes.
Once you’ve created your histogram, insert a clear photo of it in the space below.

Insert histogram below

Looking at your histogram of the densities of Liquids A and B, describe the overall pattern in the data for each liquid. What is the most frequent interval (i.e., the “tallest stack”) or what range of numbers describes the densities that most groups calculated for each liquid?

Looking at my histogram of the densities of liquids “A” and “B”, the overall pattern in the data for liquid “A” is that the interval between 0.79 g/cm3 and …show more content…

The first reason why we think is because when smelling it, it smelled like rubbing alcohol because it was very strong. The second reason is that the class average of 0.77g/cm3 and my individual density of 0.80g/cm3 are either the same or very close to the density of rubbing alcohol, which has a density of 0.80g/cm3.(Mineral oil also has a density of 0.80g/cm, but it is odorless, not like liquid “A”.

What is the identity of Liquid B? Explain with evidence.

The identity of liquid “B” is water. First, it smaller like nothing, it was odorless. Water is also odorless. Secondly, the average class density of 0.98g/cm3 and my individual density of 0.99g/cm3 are very close to the density of water, which is 1.00g/cm3z

Is density a characteristic property of matter? How do you know? Cite evidence from your own observations and the class data from this lab, and from the “Slice and Dice” Gizmo to back up your

When comparing the neutral unknown to the unknown mixture, there is a prevalent overlap in the aromatic hydrogen ppm range, presenting a distinct correlation between my isolated neutral and the mixture containing this chemical. Another indicator that was used to determine the identity of this neutral chemical was the melting range, which was tested to be 68.7 C to 71.5 C. The literature value for fluorenone is 80 C to 83 C (CITE), indicating that my compound was slightly contaminated. However, the melting point range for 1,4-dimehtoxybenzone is 57 C, and therefore, it can be concluded that the neutral compound isolated was indeed fluorenone. The contamination that caused this depression in melting point was likely due to acetone, which appeared on the H NMR spectra. Also, when weighing the watch glass after evaporating the ether the yield was not as high as predicted.

In the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.

Using the data from the first two columns, an x-y scatterplot graph was created. Analyzing the graph, a set of points that formed a linear curve were identified, and the plot of the graph was reduced to these points. This is the initial cooling curve. A second series was then added to the graph, with points that correspond to the interval when t-butyl alcohol was freezing. A trendline was then created for each of the series to obtain the equation of the line and r values.

Unknown 6- Isopropyl Alcohol We found that unknown 6 was Isopropyl alcohol. Its chemical name is isopropanol and the chemical formula C₃H₈O but is typically called isopropyl alcohol. Isopropyl alcohol is today used as a primary ingredient in rubbing alcohol. Is smells very unpleasant and is used for disinfecting pads used by medical professionals for tasks such as sanitizing small instruments, wiping down surfaces, and cleaning a patient’s skin before an injection.

Once the 24-hour period has passed then you will extract the shells from the vinegar beaker and record the mass of those shells and the shells that were not exposed to the vinegar. Record all data and observations on the chart labeling the vinegar shells “experimental” and the other two “control”. Then you will pour 100 ml of vinegar into a 500 ml beaker and 100 ml of salt water in the other 500 ml beaker. Set the timer to 30 minutes and drop one “control” and one “experimental” shell to each beaker at the same time. In your data table you will record the observations of what is happens to the shells while they are exposed to vinegar and the salt water every 5 minutes.

Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.

11) After you have prepared the dilutions, clean the outsides of the cuvettes with a paper towel. 12) Place the blank tube (tube 0) in the spectrophotometer. Since distilled water has no color it will not absorb any light so the absorbance number would be zero and this done to test the absorbance scale on the Spectrophotometer for the purpose of having it calibrated correctly. 13) Set the spectrometer to a wavelength of 530 nanometers. 14) Place the cuvettes (numbers 1-6) with the appropriate substance and record it’s reading in the data table.

Drinking Rubbing Alcohol According to the U.S. Department of Energy, rubbing alcohol, or isopropyl alcohol, is a simple, synthetically produced alcohol, comprised of eight hydrogen, three carbon, and one oxygen atom. It is has numerous medical, industrial, and household uses, and is not to be confused with ethanol alcohol found in liquor or wine. More importantly, drinking rubbing alcohol is strictly forbidden.

When I used 10 volts the standard deviation for hydrogen was 2.5+0.23=2.73 and 2.5-0.23=2.27 so the range of values is between 2.27 cm3 and 2.73 cm3 and the standard deviation for oxygen was 1.3+0.12=1.42 and 1.3-0.12=1.18 so the range of the standard deviation was between 1.18 to 1.42. When I used 11 volts the standard deviation for hydrogen was 5.8+0.20=6.0 and 5.8-0.20=5.6 so the range
