How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Analytical chemistry is more than a collection of analytical methods and an understanding of equilibrium chemistry; it is an approach to solving chemical problems. Although equilibrium chemistry and analytical methods are important, their coverage should not come at the expense of other equally important topics. The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum for exploring topics such as experimental design, sampling, calibration strategies, standardization, optimization, statistics, and the validation of experimental results. Analytical methods come and go, but best practices for designing and validating analytical methods are universal. Because chemistry is an experimental science it is essential that all chemistry students understand the importance of making good measurements.
This activity will introduce pH testing of cleaning products, citrus fruits, and …
This activity will introduce pH testing of cleaning products, citrus fruits, and then analyzes a mystery Green product. Students will compare and contrast findings to discover an earth friendly product.
The students will analyze the pH of four citrus fruits: lime, lemon, …
The students will analyze the pH of four citrus fruits: lime, lemon, orange, and a grapefruit, and then they will analyze the pH of four different types of stain removers: Shout Advanced, Spray 'n Wash Max, Oxi Clean Laundry, and Clorox Oxi Magic. Using their learned information, they will predict and then analyze the pH of a final cleaning solution Bathroom Lime & Scale Remover, which is a Green product.
Students will use two methods of determining the pH for comparison. This will be done utilizing pH litmus paper and creating a cabbage indicator solution.
Students will also read labels, list the first few ingredients, and identify sales tactics used for their products such as eye-catching phrases. (Language Arts)
Finally, students will discuss and share their results as a class. Students need to answer what do citrus fruits have to do with cleaning? What product is most effective? Students need to support their answer with data from their experiment.

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

I love this activity, and I think it is a great instructional resource for students to learn about atomic structure and counting atoms in compounds. However, I would like to add a single modification.MODIFICATION: Add the following question: How are atoms of one element different from the atoms of a different element? This resource is designed to accompany students notes, texts, and other instructional resources and provide a means to review what they have learned about atomic structure and counting atoms in compounds.
