Solution preparation from salt to solution labster quizlet

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.

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 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?

Prepare to become a solution champion! In this simulation, you will complete all the steps involved in preparing an aqueous solution of a given molarity from ammonium chloride – a water-soluble salt, from start to storage.

Use that balance

Your first mission will be to determine the exact amount of ammonium chloride needed for your solution. When the calculations are sorted, you will move to your first workbench, where you’ll find an analytical balance. You will use this instrument of high precision to obtain just the right amount of the substance. It’s a tricky procedure, but you’ll have unlimited time and attempts to get it right.

Glassware and quantitative transfer

Moving on to the second workbench, you will explore and determine what glassware will be appropriate for you to use. Your lab guide and mentor, Dr. One, will walk you through the process of preparing the solution. You will have the freedom to use the equipment as you like, but only by following Dr. One’s instructions will you be successful in making the right solution. To make sure you can always redo essential steps of the process, Dr. One will provide you with a fantastic reset button, so you can try again if you make a mistake.

Solve the preparation

In the end, only by carefully ensuring that the right amount of water and ammonium chloride is used can you make the correct solution. Are you prepared for solving how to perform a Solution Preparation?
