CHEM120 OL, Week 3 Lab


OL Lab 6: Solution Preparation: From salt to solution
Learning Objectives:
 Prepare an aqueous solution of a specific concentration from a pure salt
 Correctly use an analytical balance, a volumetric pipette, a volumetric flask, and
a measuring cylinder
 Explain the relationship between molarity and mass concentration
Introduction
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.
Use that balance
Your first mission will be to determine the exact amount of ammonium chloride needed
for your solution. When the calculations are completed, you will move to your first
workbench, where you’ll find an analytical balance. You will use this high precision
instrument 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 the 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?
Part 1: Complete the Labster Lab: Solution Preparation: From salt to solution
Part 2: Report and Reflection
Purpose: Describe in complete sentences and in your own words, the purpose of this
experiment.
The purpose of this experiment was to explore the relationship between molarity and
mass concentration by preparing an aqueous NaCl solution with a certain concentration.
The simulation also explains how to correctly use a balance and why volumetric pipettes
allow for the highest accuracy in concentration preparation.
Observations: Record three observations from the simulation.
