INTRODUCTION Investigations are the processes that will be used to describe both criminal investigation and crime scene processing distinctions between criminal investigations and crime scene. Crime scene requires strict scientific methodologies such as collections procedures and testing protocol‚ whereas criminal investigation has less of hard science character and relies more on the experience and skills of the investigator rather than rigid scientific protocols and procedures. Evidence is a

Analysis of Commercial Vitamin C Tablets Aim: To employ iodometric titration to determine the content of vitamin C in commercial tablets using volumetric analysis and compares it with the manufacturersÂ’ specifications. Introduction Vitamin C is an essential substance for maintaining good health and it is proved to be the agent which prevents scurvy. Most animals can synthesize their own vitamin C‚ but some‚ such as human cannot. Owing to the increasing concern for oneÂ’s health

Indicators can ten be used to test for the presence of acids or bases in a substance. Some are available in paper form (litmus) and others in liquid form (methyl orange).

Private investigations Private investigators can specialized in many areas of the criminal justice fields. Some of the positions are crimes against children or elderly‚ civil‚ and crimes against property. The investigations mostly private investigators carry out are observation of a suspect and conduct searches. So it goes with surveillance these days‚ which video cameras played a key role in identifying a perpetrator committing a crime. In any case‚ most surveillance involves someone before or

Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere

Genevieve Prevete Dr. Cozine Security Investigations Midterm Question 1 An investigation is a process in which there is a search inquiry for ascertaining facts. It is a detailed and careful process. There are different types of investigations‚ which come with different types of investigators. However‚ with that said the steps in an investigation are the same in every process. The process consists of five basic steps‚ identify the problem‚ gather facts‚ develop a hypothesis‚ continue

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C
