Unknown Solid Lab Report

902 Words4 Pages

When given unknown solid the main objective is to find what the unknown solid is.To figure out what the unknow solid is it was put through some tests and trial to figure out what was the unknown solid.Chemistry is part of everyday life and the reason to investigate unknown solids is to ensure we're not in contact or consume dangerous chemicals .Other people were given an unknown substance and were trying to figure out what there unknown solid was as well and there was duplicates of the same solids.The goal is to find the group that best matches our result and compare to see if the compound is the same. Introduction The physical property of the unknown substance given was a white clumpy powder.The first test was testing the electric conductivity of the substance.To show the conductivity of the substance we mixed it in water and tested the solution with a conductivity meter.To check the conductivity of the solid it was put in a small dish and was tested with the conductive meter.Then t o check solubility of the unknown solid it was mixed into a small amount of water to see test solubility.The next text was to conduct a ph test using some aqueous solution of the unknow solid we applied that to a ph paper strip to show ph.Another test was checking the solid’s reactivity.Using water mixed with …show more content…

All solids were soluble in water but the only group that didn’t was group 8.Most of the groups had a acidity of either basic or neutral acidity.The data that matches our data is group 7.Our test for the time for melting time was the solid that took the longest to melt then the group

On April 6, 2016 at approximately 11:45am, a local police station got a call about a hostage situation at a local pharmacy. When police and medical examiners got to each crime scene, they learned that all of the hostages were given drugs and had overdosed on them. Some of the pills, in powder form, were found near the victims. One of the victims was stable enough to tell the investigators that the power on the floor were the drugs they were forced to take. The medical examiner found out each hostage was given either unknown A or unknown B.

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.

The third experiment tested if the samples were made of cells. To test this factor, we put the substances underneath the microscope. By adding methylene blue to one of the two of each substance sample, you could observe if cells were present which would be a sign of life. In the experiment we observed that Vial B had cells and the Vial A did not.

In order for a substance to be a conductor of electricity it is necessary that the substance consist of electrons that are able to move around in the substance. Read the entire laboratory activity. Form a hypothesis as to whether distilled water is a conductor of electricity. Based of this laboratory activity I believe that if distilled water is tested and experimented, then it will show not be a conductor of electricity.

The first test we conducted was the electricity test to see if the object was a good conductor of electricity. We turned on the electricity conductor that was hooked up to a battery and then placed the material on the plate. We observed the lit up lightbulb colors on the conductor in order to determine if it could or could not conduct electricity, the lit up colors were a bright red and dim green

And there is some pre-lab information that found in the internet. By Experiment 3: Identification of a Substance by Physical Properties “Every substance has a unique set of properties that allow us to differentiate one from another. These properties can be classified as either physical properties or chemical properties.

The Unknown Identification Lab was an experiment that provided the opportunity to apply all the tests that were learned in the semester of lab, to identify the two bacterias that remain unknown. Gram- staining and two other tests will be used to identify the unknowns. This experiment is crucial to the understanding of each test, and can benefit in the ability to identify the characteristics of specific bacteria. Having a clearer understanding of the bacteria can further the research of bacteria for medicine, such as antibiotics. The understanding can also help the development of research in the environment.

Introduction: Microbiology is the study of the microbial world, which is composed of microorganisms that are too tiny to be seen with a naked eye. This project demonstrates the significance of correctly identifying unknown organisms with methods and techniques acquired in the laboratory as they can make or break one's ability to accurately isolate and identify various species. Studying microbes enables oneself to have an insight on not just their structure or how they function, but how they have an impact on organisms and their environment around them as they can be found nearly anywhere. The importance of the process of identifying unknown bacteria vary from determining the causative agent of a disease, to testing if a specific food or fluid is safe to consume, and simply knowing what is present

”(Schreiner 5) This explains how a simple vinegar solution can achieve conductivity. Another example of when evidence is shown when the author states, “Ammonia is such a substance. When ammonia dissolves in water, it reacts with the water and forms a few ions. This is why laundry ammonia, which is a solution of ammonia in water, conducts electricity, but not very well.”

Sludge Lab Report

The objective of the sludge lab was to determine how many different pure substances were in the sludge by using the methods and techniques we have learned throughout the year. We had to pick separation methods so we could separate our sludge and then test characteristic properties on our separated liquids and solids. This experiment made us use our knowledge on characteristic properties to pick the ones we should test to help us identify our pure substances. Characteristic properties are properties that help identify a solid or liquid. Each solid or liquid has a certain density, boiling point, solubility, flammability, so if you know what each one is then you can use that information to help you identify your solid or liquid.

Explain How Does The Strength Of Bonds Within A Molecule Affect Its Melting Point

Distilled water is an ineffective conductor of electricity because since it is purified water, it contains very little ions, and its molecules do not have free electrons to travel which is necessary to transfer current. There isn’t much of a difference between the conductivity of the tap water and distilled water because both tap water a distilled water go through many processes to ensure that it is detoxified and safe to drink/use, which means that it as well will contain many ions. Therefore, both distilled water and tap water display low electrical conductivity. 7. List the physical properties that indicate ionic bonding exists in a

Tap water can contain other substances, therefore might affect the electrical conductivity. However, it probably did not have that much of an effect because they kept the solvent (tap water) controlled throughout the experiment. They did not use tap water for some trials and distilled water for other trials. Something I found difficult in carrying out the method was to make sure that the amount of substance is exactly 10g (or 30g or 60g).
