Exercise 10: Acid/Base Balance Worksheet Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.4 2. At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No Activity 2a: Hyperventilation – Run 1 1. At 20

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

Acid Rain: The Southern Company (A) Problem Statement In 1992‚ executives at the Southern Company have three years to formulate a robust and complex strategy that will involve massive capital outlay and substantial modifications to processes and procedures as it works to comply with provisions enacted in 1990 to the amendments of the Clean Air Act‚ while simultaneously ensuring they remain sustainable and profitable. Analysis The Southern Company is an American based electric utilities

Acid Rain Lab Report Introduction: The problem was to see how crushed chalk and whole chalk weather differently. The independent variables are The temperature of the liquids The surface area of the chalk‚ crushed vs whole The dependant variable was the weathering of the chalk; this was calculated by measuring the foam reactant. Procedure: Part B- For the two partners recording data with the room temperature liquids‚ the materials where collected first. Two of the graduated

My drug is LSD (Lysergic Acid Diethylamide) 2. Usually LSD is taken by mouth. It is dissolved into a liquid and soaked into blotter paper‚ which is then cut into quarter inch sized doses. These are also called tabs‚ trips‚ or hits. Although it is less common‚ LSD powder can also be squeezed into tiny pills‚ called microdots‚ or placed into capsules. The liquid itself can be squeezed into the eye. 3. LSD is manmade. 4. Battery Acid‚ California Sunshine‚ Dots‚ Golden Dragon‚ Pane‚ Looney Toons

Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due

Acid Rain: The Southern Company (A) Case Study #1 2/01/2012 Situation: The acid rain provisions of the 1990 amendments to the Clean Air Act were to being in 1995. Currently‚ it is 1992 and The Southern Company (a electric utilities holding company operating in Georgia‚ Alabama‚ Mississippi‚ and Florida) had to decide what actions they were going to take in order to comply with the new regulations. Before the Clean Air Act‚ firms did not have incentives to reduce emissions below the government

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance
