About the Solution Preparation: From salt to solution Virtual Lab

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?
