It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can be used to

At the start of the experiment‚ we prepared standards of benzoic acid solutions that contained 2‚4‚6‚8‚ and 10 mg/L in 0.10M HCl‚ our group prepared the 6 and 6 mg/L standards for all the groups within the laboratory. In one of the 100mL volumetric flask it contained 6 mg/L benzoic acid + 10 mL HCl‚ then diluted to the mark on the flask with DI Water. In the other 100mL volumetric flask it contained 8 mg/L benzoic acid + 10 mL HCl‚ then diluted to the mark on the flask with DI water. Standards

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

Exercise 6: Acid-Base Titrations Nick Redmond Partner: Stephan Villavicencio Thurs. Section Lab date: March 19‚ 1998 Report date: April 6‚ 1998 Abstract: The equilibrium between acids and bases during a titration can be used to determine several characteristics of the acid or the base. Sodium hydroxide was standardized to 0.1035 M in three acid-base titrations of potassium hydrogen phthalate (KHP). This standardized NaOH solution was then used in a series of other titrations with acids in order

Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these changes can be related to everyday life

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

The control Petri dish was left alone and a pipette was used to deliver several drops of acetic acid to the experimental dish. Several drops of sodium hydroxide were added to the experimental dish. Results were observed and recorded. At station 2 the control Petri dish was left alone on the table
