About Acids and Bases: Acidity and alkalinity in everyday substances Virtual Lab Simulation
Have you ever consumed an acid or a base? Yes you have! Acids and bases are found all around us: In the food we eat, the beverages we drink, many of the everyday household products at home and even inside us! In this virtual simulation, you will learn the fundamentals of acids and bases and go through some of the ways they can be characterized and used in the lab.
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.
In order to determine what reactions occur when you mix acids and bases of different strengths, you will have the freedom to mix solutions of these and interpret the resulting salt reaction 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 to measure the acidity of various substances around you?
