Determining the Identity of an Unknown weak acid (Vernier) Formal Lab Report Kelli McWatters August 7, 2017 Chem 1121 Dr. Reed Objective: Observe and measure a weak acid neutralization and determine the unknown identity of an unknown acid by titration. Introduction: Within an acid-base titration the titration curve resembles the strengths of the corresponding acids and bases. A strong acid will correspond with a weak conjugate base, and a weak conjugate acid will correspond with a
BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates, lipids, nucleic acids, and proteins. In today’s lab, we will be studying three of the four-proteins, carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed, the test is considered positive
Objectives: • To conduct a reaction between solutions of a weak acid and sodium hydroxide. • Determine the half-way point of titration of an acid-base reaction. • To calculate the pKa and the Ka for the weak acid. • To calculate Molar Mass of a weak acid from the titration results. • To determine the identity of a weak acid. Introduction: The purpose of this experiment is to identify an unknown weak acid by titration with a standard sodium hydroxide solution. The pH of the titration solution will

Introduction: a) Title: The Establishment of a Chemical Equation Using the Method of Continuous Variation. b) Purpose: the continuous variation method is used to establish a chemical equation by displaying on a line graph the change/difference in temperature caused by the composition of acids and bases in the solution. II. Apparatus and Materials: A) Goggles B) Acid C) Base D) Digital Thermometer E) Pipet
The Environmental Protection Agency (EPA) has come to the lab group to investigate an abandoned chemical company. In specific, an unknown compound is to be investigated and identified. The lab group takes this goal a step further and also compares it against products found around the member’s homes. Multiple titrations will be performed, both with use of the PASCO program and by manual indicator. Through these experiments, different calculations will be performed to help in the analysis. In addition
Not only is it important in a lab setting but as well as in healthcare in general. Properly identify what strain of bacteria a person has will aid in the proper medicine and dose given. Throughout the semester we have learned about different types of bacteria and certain test that can clearly identify them. The purpose of this lab report is to identify a Gram-positive or Gram-negative bacterium. Using all the knowledge of procedures and lab techniques identify the unknown and discuss all the tests you
Unknown White Compound Formal Lab Write Up Kimberly Jeong Group Members: Xavier Baxter Branica Xiong Andrew Lyons Abstract The purpose of this experiment was to identity, analyze and synthesize an unknown white compound. The identity of the unknown compound was determined by a flame and ion test to identify the cation and anion present in the compound. To confirm the identity, an ammonium test and conductivity test was conducted. After, the unknown compound, which was identified as

2046L Lab Report: Antacids Katie Wong Lab Partner: Kealie Do June 27, 2017 Abstract: The build up of stomach acid may cause irritation and excess pain to individuals. Luckily, antacids being a weak base can help relieve the symptoms and pain. Antacids, such as Gelusil, Medi-Firs, Alka Seltzer, and Alcalak are neutralizing agents of acids that become helpful to the human body when heartburn occurs. Heartburn, also known as acid reflux is a common medical issue that occurs when hydrochloric acid (HCl)
