Police Need The Identity Of An Unknown Substance Essay

I chose the Federal Bureau of Investigation for my career choice. According to the Mission and Priorities page on the Federal Bureau of Investigation’s website, the purpose of the Federal Bureau of Investigation or FBI is to, “Protect the American people and uphold the Constitution of the United States (“Mission & Priorities”, n.d.). The FBI ensures this specific purpose by completing the following: “protect civil rights, combat transnational/national criminal organizations and enterprises, combat major white-collar crime, and combat significant violent crime” (“Mission & Priorities”, n.d.). As of right now, “the FBI has around 35,000 employs which includes special agents and support professionals” (“Mission & Priorities”, n.d.).

The results that the experimenters learned in this lab is used all through the world during police investigations. The police can use DNA fingerprinting and gel electrophoresis to find the innocent suspects of a crime. To find the DNA to use, the police can use blood or hair strands that were found at the scene. If the DNA in the gel are a match, the evidence found came from that suspect. In conclusion, DNA fingerprinting and gel electrophoresis are a mechanism for police to use throughout an investigation. Both provide accurate data for the police to use to eliminate

The primary goal of this laboratory is to correctly identify an unknown substance. To achieve this task, one may use various tests that reveal both chemical and physical properties of a substance. By comparing the results of a known substance and the unknown substance, one may eliminate alternative possibilities and more accurately predict the undisclosed compound. Furthermore, by performing these tests, data can be collected and verified regarding chemical and physical properties of the unknown. Understanding the chemical properties of a known substance aids one’s understanding of the unknown based on comparative analysis of the results of the tests.

Purpose: To use indicators to test for the presence of organic compounds in certain substances.

Many different drugs such as street drugs are mixed with a lot of simple household items, such as sugar, starch or quinine. The forensic scientist must be able to tell the difference between the substances. Many court cases that involve drugs rely exclusively on the forensic scientists findings. They must be able to prove that the substance found was actually a drug and not say a package of sugar or another legal

Mr. Brie was convicted of the manufacturing and distribution of a controlled substance analogue in violation of the Controlled Substances Act (CSA) and the Controlled Substance Analogue Enforcement Act of 1986 (Analogue Act), federal statutes, 21 U.S.C. §§ 802(32), 812, 813, 841(a), & 841(b)(1)(C) (2012), which is an offense that has a scienter element the Government has the burden of proving. McFadden v. United States, 135 S. Ct. 2298 (2015). The scienter element is developed through the following relevant provisions. A controlled substance analogue is defined as a substance which: 1) the chemical structure is substantially similar to schedule I and II substances, 2) has effects similar to (or greater than) those of substances that are schedule I or II, or 3) is

The first part of the Identification and Synthesis of an Unknown Ionic Compound (Project 3 Week 1) experiment was to determine the unknown compound #202 that is given to the experimenter. The second part to the experiment (Project 3 Week 2) was to discover different tests the experimenter can conduct in order to prove that they have the specific ionic compound that they discovered in part one. Some of the ways that the experimenter can determine the unknown compound #202 they have includes, preliminary tests, physical state tests, solubility testing, analysis of anions, analysis of cations and flame tests (Dealing with Unknown Compound). There are many ways an experimenter can determine the ionic compound that they have, including pH tests, flammability tests (liquids and solids), solubility tests and heavy metal tests, just to name a few (Identifying Unknown Chemicals in Science Labs).

Inside of the case was a plastic container containing approximately one gram of a green leafy substance, which was field tested for marijuana with a positive result. There was also a pipe and scale containing a small amount of marijuana. There was a baggie containing a white pill marked “E 79” in the case as well. I asked Elias if the pill was methadone or hydromorphone and he replied it was just something he took to fall

Roasting is the most precise method, of the three conducted in the lab. The data found by each lab group was averaged with three other groups to find the unknown mineral.

The DEA can also take samples of any controlled substances on the premises. The pharmacy should take duplicate samples for review and testing. The investigator should be able to tell the pharmacy representative where the testing will be done. Plus, the investigator should provide a receipt for any samples taken. The pharmacy can request reimbursement of samples of expensive materials.

The purpose of this lab is to use chemical and physical properties to identify a material. We are working on observing, inferring and predicting. We are learning if the properties of materials that appear similar can be used to tell them apart.

It can also determine whether drinking water meets legal purity requirements. Presently the vast majority of the legal researchers are specialists that get pieces of information from the wrongdoing scene. Culprits regularly don't plan out a robbery or burglary and thoughtlessly abandon unmistakable hints that permit an agent to track them moderately effectively. Regardless of the possibility that the criminal is extremely cautious all through their wrongdoing, there will be some hint of their vicinity at the wrongdoing scene. There are numerous ranges of legal sciences, which incorporate general wrongdoing scene examination, criminological science, scientific toxicology, measurable pathology, hereditary fingerprinting, and chromatography.

We will use three tests to determine the makeup of the compound: iodine drops, vinegar tests, and flame color. For the iodine test we will put a drop of iodine into the mystery substance and record the results. Iodine is an indicator, which means that it is a substance that shows the presence of a certain material (dictionary.com 2). When iodine comes in contact with starch, it becomes a blue-black color. For the vinegar test, a drop of vinegar will be dropped into the substance. If it fizzes, then it is baking soda. For the flame test we will burn a dissolved sample of the substance. When a molecule gains energy, the particles gets

An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed to some reagents. Classification is based on whether there is formation of precipitates or not when metal cations react with the reagent. The five groups of cations and the characteristics of these groups are as follows:

The United Nations Office on Drugs and Crime (UNODC) recently revealed that new psychoactive substances are emerging in the market in terms of both quantity and diversity. However, the paucity of data on the harmfulness and prevalence of these substances offer a challenge in facilitating risk assessment at the international level.
