CHEM120 OL, Week 4 Lab OL Lab 7: Ideal Gas Law Learning Objectives Explain the physical concepts of temperature and absolute zero Define the relationship between pressure, volume and temperature in gases using gas thermometry Apply the Ideal Gas Law Give examples of acids and bases from everyday life Define pH and identify acids and bases using the pH scale Apply the Bronsted-Lowry definition of acids and bases to chemical compounds Describe the amphoteric and self-ionization capacity of water Calculate the pH of a strong acid and base in solution Assess whether a neutralization reaction will occur Evaluate the outcome of simple acid-base reactions Introduction Do you know that you can save a life using the ideal gas law? In the Ideal Gas Law simulation, you will define the physical concept of temperature and absolute zero. You’ll learn about the relationship between pressure, volume and temperature in gases using gas thermometry. Explore your workbench Your first mission in the Ideal Gas Law simulation will be to have a look at the equipment at your disposal and acknowledge what you would need for your experiment. Learn the roles of each piece of equipment and how they will play a part in your gas thermometry. Experiment with gas thermometry Handling extreme temperatures is not a hazard as long as you’re a part of this simulation! Observe the changes in the pressure of an ideal gas as you cool it down from the temperature of boiling water to the temperature of boiling nitrogen. You are lucky you’re in a virtual lab as this means you can speed up time for the pressure to reach equilibrium! You will have complete freedom to repeat the experiment with any amount of gas and to define the absolute zero temperature. Are you ready to apply the Ideal Gas Law and everything you learned in gas thermometry in order to assist the transfer of an organ for a transplant surgery? Report back to the paramedics Once you have completed your experiment and have collected all of your data, your final mission would be to share the results with the paramedics so that they can keep
CHEM120 OL, Week 4 Lab the organ safe and sound in the correct pressure and temperature conditions to make it all the way to the hospital. Acidic life How do acidic or alkaline foods affect the pH of our blood, and what does this even mean? Together with your lab assistant, Marie, you will explore different concepts of acids and bases, and investigate how alkaline foods can also contain acids. You will measure the pH of solutions, and dive into these to experience what happens at the molecular level. Salty mixtures In order to determine what reactions occur when you mix acids and bases of different strengths, you will have the freedom to mix these solutions and interpret the resulting salt products. And don’t worry if you make mistakes – in this virtual lab, you can just reset and start over! On-the- go quizzes will make sure you are up to speed, and you can always dive into the theory pages for more in-depth explanations. Corrosive everyday chemicals Acids and bases can be corrosive and very dangerous to handle. But they also play a fundamental role in all living things, in nature, and in the chemical industry. Will you be able to measure the acidity of various substances around you? Part 1: Complete Labster lab: Ideal Gas Law: Apply to Save a Life 1. Purpose: Describe in complete sentences and in your own words, the purpose of this experiment. The purpose of this experiment was to gain knowledge of how to determine what chemicals are acidic and basic. Also, what happens when pressure is decrease or increased. 2. Observations: Record three observations from the simulation. I. pH ranges between 0-14. It can go below zero. II. Acids donate a hydrogen ion III. Bases accepts a hydrogen ion
CHEM120 OL, Week 4 Lab 3. If the pressure of a fixed volume of gas decreased in a sealed container, what variable would you think changed? Did this variable increase or decrease? If the pressure in a sealed container decreased, the volume would increase. 4. Why is it important to convert into units of Kelvin before using the Ideal gas law? It is important to convert into units of Kelvin before using the Ideal gas law because the temperature scale is in Kelvin and the answer must match the units. 5. Using what you learned in this simulation, explain why compressed gas cylinders, such as those found in the hospital, typically contain a warning to not leave in sunlight or expose to heat. The heat can cause the gas inside the cylinder to expand, causing increased volume and possible an explosion. Part 2: Complete the Labster lab: Acids and Bases 1. In your own words, describe how to determine which substance acts as an acid and which substance acts as a base in the forward direction of the following reaction: H 2 S + H 2 O ⇌ H 3 O + + HS - To determine whether a substance is an acid or a base, count the number of hydrogen ions on each substance before and after the reaction. If the number of hydrogen ions increase, it is a base because bases accepts hydrogen ions. If the number of hydrogen ions decrease, it is acidic because acids donate hydrogen ions. 2. Predict the two products of the following neutralization reaction and label each product using acid/base terminology: HCl + RbOH → RbCl (Acid) + H2O (Base) 3. In your own words, describe the relationship between proton (H + ) concentration, and pH. The higher the H+ concentration, the lower the pH is. 4. Reflection: Consider what you learned from this simulation. Reflect on three to four key concepts that you learned in this lab exercise. How could the lessons learned in this virtual lab related to a real world situation in the community/world or your future career? Be specific in your answer (this should require 5-10 sentences).

CHEM120 OL, Week 4 Lab Knowing how to determine the pH of solutions is extremely important in healthcare. It helps to determine an organism and how to treat that organism. It also lets you know if something is off in the body. For instance, the pH of urine is between 6-7. Having a pH lower that this may suggest renal function. This gives the physician a starting point of treatment.
