When I first heard about a calorimeter, I had no idea what it was or what relevance it would have to me and my major. Before I delve into the relevance of calorimetry though, let’s first talk about what it is. Calorimetry is the science of measuring the amount of heat transferred to or from a substance in a reaction by using a calorimeter to measure the heat exchanged with the surroundings.

Acid/Base Titration: An Example

As a student, when I was taught titration, it was accompanied by a long laundry list of scenarios: titration of a strong acid with a strong base, titration of a strong base with a strong acid, titration of a weak acid with a strong base, and titration of a weak base with a strong acid. Each of these scenarios were followed by a graph that corresponded to changes in pH, like the following

The electrochemistry unit at CU begins with redox reactions. Make sure you understand the basics of this before continuing through this article.

A voltaic cell, a.k.a. a galvanic cell, requires several parts. In official terms, you’ll need a cathode, an anode, and a conductive substance (usually wire) and salt bridge connecting the two. Less formally, you’ll need
