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

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

Purpose: Describe in complete sentences and in your own words, the purpose of this experiment.

This lab's goal is to ensure that we understand how temperature and molecular concentration might impact many scenarios, whether they occur in a clinical environment, a lab, or even in everyday life. We also learned about the Ideal Gas Law and how to use it correctly……….. Continue
