CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

1. What is forensic science? the application of science to the criminal justice system. 2. What three tasks or responsibilities does a forensic scientist have? collect and analyze the evidence found at a crime scene‚ apply the techniques from the physical sciences and use their knowledge of these areas in order to make sense of the evidence that has been collected from a crime scene‚ interpret the evidence. 3. What criteria might be used to establish someone as an expert witness? consideration

Crime Library » Forensics and Investigation Ballistics In forensic science ballistics‚ the study of motion‚ examines the dynamics‚ angular movement‚ and effects of projectile units such as bullets‚ missiles‚ and bombs. There are many applications of ballistics within a criminal investigation. Bullets that have been fired at the scene of any crime will be examined in the hopes of discovering several pieces of information. The actual bullets can identify what type of gun the criminal used and

Doreen Garber Week 6 The first and most important step in any crime scene investigation is to secure the scene. It sounds easier than it really is. The scene includes possible witnesses‚ victims and suspects. Securing the scene includes keeping unauthorized personnel from walking through the scene. The most common contamination results from police‚ ems‚ victims and witnesses. The best thing that can happen to a crime scene once it has been secured is nothing. Once the scene has been secured

MATH INVESTIGATION 4.2 FACTORIZATIONS on the Math Investigator determines if a number is prime or composite. If a number is composite‚ it prints all its factors‚ the number of factors‚ and its prime factorization. The numbers 1‚ 2‚ 4‚ and 6 have 1‚ 2‚ 3‚ and 4 factors‚ respectively: 1 has only 1 as a factor; 2 has 1 and 2 as factors; 4 has 1‚ 2‚ and 4 as factors; and 6 has 1‚ 2‚ 3‚ and 6 as factors. These factors are illustrated by the rectangles shown here. Starting Points for Investigations

have probably heard the term “forensic science” at least once. Forensics is a very important area of science‚ mostly dealing with crime scene analyzation to figure out the basic questions of “who did it?” and “how did they do it?” I personally plan on being a forensic analyst in the future‚ so I was very excited at the prospect of writing this speech in order to do much research on one of my favourite subjects. Arguably one of the most important factors in forensic science is the chemistry behind

Forensic Science The forensic science field has many aspects that contribute to it. This field contains many subfields. For example‚ forensic pathology‚ psychology‚ and anthropology. They all have different statistical references‚ like crimes committed in a certain country‚ or the number of bodies that are found in every year. They are all different‚ but comparable in one way. These subfields are within the forensic science discipline and deal with human beings. Forensic science‚ also called forensics

than today. In addition to samples taken from a body‚ what other information or evidence could point to poisoning as the cause of death? Coloration of the body or things around the body indicating poison intake. What are the challenges for forensic scientists in identifying poisons? First‚ determining if there was poison involved in the first place‚ and also‚ it would be difficult to have to run so many different tests to see which poison it was.

major contribution to forensic science. He was the first person to use fingerprints as groundwork in criminal cases. It was his study of details in prints to compare them with others. He also provided the first workable fingerprint classification system (Unknown‚ n.d.). The “father of forensic toxicology” is Mathieu Orifila. He was the first great 19th-century advocate of forensic medicine (Unknown‚ 2012). He worked to make the study of chemicals a routine part of forensics. He is recognized
