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 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.

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.

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.

Phosphate Buffer
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.
