The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

Example Lab Report Experiment 4 1. Judith Anthony‚” Strong Acid/Strong Base Titrations”‚ CHEM 1130‚ T.A-Joseph Kreft‚ Tuesday 8am‚Room 1871‚Donna Ellitnorpe. 2. Purpose of this experiment: The purpose of this experiment is to observe the neutralization reaction that occurs between strong acid and strong base solutions. The technique of titration is used to observe the acid content of the fluid in a car battery. 3. Procedure: Calculate the volume of 6.00 M NaoH that is needed

This project’s purpose is to find the effects of UV light on Staphylococcus epidermidis‚ furthermore recognized as staph infection. Staph infection is an infection usually acquired on the skin that can promote fever‚ nausea‚ pain‚ boils‚ and can lead to MRSA‚ which can lead to death. Because there is no cure for staph infection‚ this experiment called for research on clinical trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally

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

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid) and

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

Polypeptides‚ better known as proteins‚ carry out nearly all of a cell’s functions. A protein is made up of at least one or more amino acid polymers. The necessity of proteins for life is unequivocal‚ not only do they help to form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell

Introduction Energy is needed to be applied to a solid compound in order to changes its state point of a compound. The actual purpose of the experiment is to determine the measurement and the melting points of the benzoic and mandelic acid and various mixtures of mandalic and benzoic acid‚ and an unknown
