acids/bases

How do you demonstrate the workings and effectiveness of buffers in your acid-base unit?

Citric acid is a weak tricarboxylic organic acid. It is highly soluble in water and, once it dissolves in that, it shows weak acidity but a strongly acidic taste which affects sweetness and provides a fruity tartness for which it is widely used to complement fruit flavors in the food and beverage industry.

Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them.

I have taught at three different public schools in the United States (two in California and one in Washington state), and now three different international schools (two in Thailand, one in Romania) - and at each school I have honed my practice as a chemistry teacher based on interactions and feedback from students, the strengths of the school, and the e

The unit of acids and bases is difficult for most students in Advanced Placement Chemistry. The variety of various calculations can be overwhelming. I decided it was time to make the pH calculations more exciting.

I try to examine activities an multiple levels. First on the list, I want to know if my students will be engaged and learn something. Second, how difficult is it for me as a teacher to actually pull it off? One of the most important questions...are the students learning chemistry or just having fun?
