Chemistry Laboratory Safety Rules
Make your chemistry laboratory experience safe by following these simple rules.
How to Write a Lab Report
Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report, use that. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report.
How To Keep a Lab Notebook
A lab notebook is your primary permanent record of your research and experiments. This is a list of guideline that explains how to keep a lab notebook.
Science Lab Report Template
If you are preparing a lab report, it may help to have a template to work from. This science lab report template allows you to fill in the blanks, making the lab write-up easier.
Chem Pre-Lab: How to Prepare for Chemistry Lab
Chemistry lab is a required component of most chemistry courses. Learning about lab procedures and performing experiments helps you to learn...
Chemistry Laboratory Glassware Gallery
Learn the names and uses of different types of chemistry laboratory glassware.
Lab Equipment & Instruments
Find images of laboratory equipment and instruments, including glassware and antique items.
Do the units for solution concentration confuse you? Get definitions and examples for calculating percent composition by mass, mole fraction, molarity, molality, and normality. I've also included a bit of information on dilutions.
Solubility Rules for Inorganic Compounds
These are the general solubility rules for inorganic compounds, primarily inorganic salts. Use the solubility rules to determine whether a compound will dissolve or precipitate.
Calculating Solution Dilution
Here is a worked example of how to calculate a dilution of a stock solution.
Chemical Storage Color Codes
This is a table of chemical storage code colors. These are the J. T. Baker standard color codes for the chemical industry.
Lab Accidents and Lab Stories
Do you have any tales to tell of lab experiments gone very wrong or lab accidents you have witnessed? What is the most dangerous thing you have ever seen someone do in a lab? Here's your chance to share.
How to Dry a Graduated Cylinder
Learn how to dry or pre-rinse a graduated cylinder for use in chemistry lab.
How to Read a Meniscus
The meniscus is the curve seen at the top of a liquid in response to its container. When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the meniscus. Here's how to read a meniscus.
Laboratory Safety Quiz
Are you a safe scientist or a menace to yourself and others in the chemistry lab? Here's a ten question quiz you can take to test yourself. It's sarcastic and maybe even a little mean, but... some accidents just shouldn't happen.
Is It Safe to Use Kitchen Glassware for Chemistry?
Is it safe to use your kitchen glassware and utensils for chemistry experiments? Here's a look at some of the risks involved in using your dishes for chemistry.
Incompatible Chemical Mixtures
Here's a list of chemicals that you don't want to accidentally mix, together with brief statements about the expected reactions. Use this information to avoid accidents and ensure safe storage and handling of potentially dangerous substances, both at work and at home.
Perform the Mohs Test
The Mohs test is one way to determine the hardness of a rock or mineral. You can use the Mohs hardness to help identify an unknown specimen. Here's how you can do the test yourself.
Science Laboratory Safety Signs
This is a collection of safety signs and symbols commonly seen in a science laboratory, particularly a chemistry lab.
Using Material Safety Data Sheets
Material Safety Data Sheets (MSDSs) aren't just for chemists! From your About Chemistry Guide, this tutorial for the non-technical consumer defines MSDSs, describes why you should know how to use them, tells how to find them, and outlines typical uses. Links to related topics are included.
pH of Common Chemicals
Here's a table of the pH of several common chemicals. You can use the list to set up color ranges for pH indicators or simply to learn more about acids and bases.
It's easy to make a saturated solution for chemistry lab or growing crystals. Here's a look at what a saturated solution is and how to prepare one.
Bad Lab Partners
Have you ever taken a lab class and had lab partners that didn't do their share of the work, broke equipment, or wouldn't work together with you? This situation can be really hard, but there are steps you can take to make things better.
A phosphate buffer is a handy buffer solution to have around, especially for biological applications. Because phosphoric acid has multiple dissociation constants, you can prepare phosphate buffers for any of the three pHs.
Lab Partner Stories
Your lab partners can make or break a lab class. Share your experiences with a good or bad lab partner. Or were you the bad partner? Here's your chance to praise your partner or vent your frustration.

Grasp the basic chemical concepts of titration, a technique used to determine the molarity of an acid or a base.
Cutting Glass Tubing
Glass tubing is sold in a variety of lengths. There is a good chance you'll need to cut it, so here is what to do.
What Is Distillation?
Distillation is a common chemistry process used to separate materials by changing their states of matter. Learn more about how the process works and find out about different types of distillations.
Glass tubing is used to connect other pieces of lab equipment. It can be cut, bent and stretched for a variety of uses. Here is how to work glass tubing safely for a chemistry lab or other scientific laboratory.
How To Set Up Distillation Apparatus
Distillation is a method of separating or purifying liquids based on their different boiling points. Here is an example of how to set up a distillation apparatus.
