Review Sheet Exercise 12 Serological Testing NAME Kali Rothfuss LAB DATE/TIME 6/22/11 Positive and Negative Controls 1. Why are there a number of washing steps in serological tests? The are a number of steps needed in order to remove any non specific binding that may have occurred. 2. Describe how you would know that you had a “false positive” result. What does this mean for the rest of your results? A positive result with a negative control indicates a “false positive”

Acids‚ Bases‚ and Buffers Introduction: The pH scale is used to determine how acidic or basic a solution is‚ ranging from 1-14. The most acidic of all acids are at a pH level of 1 and the most basic of all bases are at 14. The neutral pH level is 7‚ which is what drinking water is. The pH level is determined by the amount of H+ ions present in a solution‚ and the more H+ ions there are the more acidic it is‚ and the lack of these ions results in more basic solutions. One distinguishing feature

when atoms in a molecule share a pair of electrons. For example‚ “the atoms in sugar do not form ions; instead‚ they are held together because of shared electrons.” 3. Do you think sugar or salt will melt at a higher temperature? Explain your answer. Since sugar is composed of covalent bonds and salt composed of ionic bonds‚ I think salt will take a higher temperature to melt because salt is bonded together by stronger bonds. Ionic bonds are much stronger than covalent bonds. Covalent bonds

Date Due: July 5‚ 2013 Date Submitted: July 5‚ 2013 EXPERIMENT 1 PREPARING BUFFERS AND BUFFER CAPACITY INTRODUCTION A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base‚ in relatively equal and "large" quantities. A buffer system can be made by mixing

Rodney L. Bennett Jr ISSC362 Week 1 Lab #2: Implement Hashing and Encryption for Secure Communications Instructor Name: _Adam Meyer_ Lab Assessment Questions 1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. The hash file is changed when the data is modified because the information within the file has changed and it is considered a new/different file. 2.

Irresistible? By Mikayla Messing 8/3/12 Section 623 Abstract To examine the effectiveness of buffers by titrating two sets of five different solutions using HCl and NaOH and monitoring the pH change of the various solutions. The data collected shows that the buffer systems made with sodium acetate and acetic acid were effect when titrated with the strong acid and the strong base. Comparison of all the solutions shows that the concepts of buffers holds true for the results from the experimentation
