Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

estimated visits were 19‚221. The DEA laboratory system seized and analyzed over 1.3 million hydrocodone tablets in 1997. Since hydrocodone is considered to be morphine like in every aspect‚ it is easy to see why one may choose to use and abuse this substance. For the hydrocodone abuser‚ the quickest way to feel the effects of vicodin is to snort it. The way that vicodin acts on the brain can cause it ’s user to experience feelings of euphoria. Snorting vicodin speeds up the usual effects‚ and brings

Substance abuse over college students make up one of the largest groups of drug abusers nation wide. Daily drug abuse among college-aged young adults is at its highest since 1980. College students are abusing a number of prescription drugs‚ over-the-counter drugs and illegal drugs‚ Adderall‚ alcohol‚ OxyContin‚ and medical marijuana. Substance abuse is defined as a pattern of drug use leading to significant problems or distress. Substance abuse among college students is not new‚ but behavior experts

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

Substance abuse in America Introduction America has a problem with drugs. In order to understand the problem‚ we first need to understand what is considered a drug. It is “any ingestible substance that has a noticeable effect on the mind or body”. (Schmalleger‚ 2011) Drugs are used for medicinal as well as recreational purposes. Unfortunately both types of drugs have played a role in American culture. Drugs have been part of the American culture as far back as the 1800’s. Using drugs for
