Experimental Determination of Avogadro's Number
Did you know that Avogadro's number isn't a mathematically derived unit. The number of particles in a mole of a material is determined experimentally. This easy method uses electrochemistry to make the determination.

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.

Introduction to Qualitative Analysis
Qualitative analysis is used to identify the chemical species in an unknown substance. Introductory qualitative chemical analysis exploits the unique characteristics of the elements to separate metal ions in an aqueous solution. This article identifies the main metal groups, discusses characteristics of major reagents, and lists selected cation complexes.

Titration Curves
Titration is a technique used in analytical chemistry to determine the concentration of an unknown acid or base. For all acids, the shape of the graph plotting pH against volume of base titrated fits the same general shapes.
