The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

Kavanagh Chem 106b‚ Section 001 Lab Performed 8th‚ 2012 Lab Report Submitted February 22nd‚ 2012 Abstract The purpose of the lab was to determine the order of reaction for the dye Red #40. By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach completion. By comparing two solutions of dye that have different

Reverse Transcription Polymerase Chain Reaction (RT)-PCR Employing PCR-based procedure in analyzing RNA would require cDNA to be synthesized using reverse transcription. When reverse transcription and polymerase chain reaction are combined together‚ it will permit detection of low abundance RNAs. RT-PCR is distinct from Real Time Polymerase Chain Reaction (qPCR). The latter measures the amplification of DNA in quantitative way and it uses fluorescent

activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This experiment is carried out to find the effects of temperature

Experiment 3: ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer
