titration

The disappearing rainbow¹ is a wonderful chemistry demonstration previously featured here on ChemEdX.^2-4 In this experiment, a colorless solution of NaOH is poured into a row of flasks, each containing a different acid–base indicator.

The purpose of this article is to show how a microtitration can introduce Honors Chemistry students to titrations.

Gentle Reader, our story today follows a number of storied histories, most conspicuously in the representation of transformation—making and breaking bonds—in a chemical reaction. Flowcharts, which use arrows to dynamically illustrate a process, also have a storied history, particularly in programming in Computer Science. Titrations have a stor

We’re coming close to the end of our Interactive Notebooking journey – this is my second to last unit – Acids and Bases. As a continuing theme from earlier, I am moving to focus more on particle view diagrams in combination with symbolic representations and macroscopic observations.

This is a procedure for a titration experiment suitable for use both at home and in supervised high school or first-year college laboratory settings. Other than an inexpensive pH meter, all materials should be easily available for students to purchase at local stores.

The major constituent of a KoolAid or a similar non-carbonated soft drink will probably be either citric acid, malic acid, or a mixture of the two acids. Either of these two weak fruit acids provides a pleasant taste and an acidity level that makes the drink palatable.

Can Alkaline Water Change Body pH?

Recently, Anne Schmidt and I published an article together in the Journal of Chemical Education.¹ The article outlines a titration activity that students can carry out at home using only store-bought items. The objective of the activity is to determine the amount of Mg(OH)₂ in milk of magnesia.

Molecular kits are a large investment for a chemistry classroom and often they only get used once a year during a VSEPR activity. My students love to play with molecular kits as it reminds them of building with LEGOS.
