There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
A 5-Star Customer Review of Chemistry on a Budget at amazon.com states:
“[S]traight forward, to the point, using household chemicals…this is the lab book for you.
I teach high school chemistry and this is exactly what [I] was looking for. Labs included simple household chemicals that could be easily found. Nice format, easy to follow along procedures, and touches on every topic of our chemistry curriculum.”

“Chemists from Martin Luther University Halle-Wittenberg (MLU) have found out how stubborn pollutants in water can be disintegrated easily and cost-effectively. To do so researchers only need a green LED light, a catalyst and vitamin C. In this way, they can produce special types of electrons that reliably destroy the pollutants in the water. “https://www.sciencedaily.com/releases/2018/02/180207120631.htm
“Researchers in photochemistry are working on the question of how light can be used to initiate chemical reactions. ‘The idea is that light penetrates a molecule and triggers a reaction there’, says chemist Professor Martin Goez from MLU, whose research group developed the new process. Of particular interest are electrons, which are released by the light energy from their molecular compound in vitamin C and then exist freely in the water.”
“Until now, expensive and complex high-power lasers were required to generate these types of electrons. Using this kind of equipment is also linked to strict safety precautions. In contrast, the development made by Goez’ team at MLU is significantly easier and more cost-effective. ‘Our system consists of a standard green light-emitting diode, traces of a metal complex that act as a catalyst and vitamin C. This method can be taught to undergrad students at a very early stage’ says the chemist Goez. The research group tested the new method on chloroacetic acid, an extremely toxic and very stable substance. With their system, the researchers were able to destroy the compound into its harmless components. They were also able to demonstrate that their cost-effective alternative could generate just as many electrons as a high-power laser.
This article is brief and could be used for a Homework assignment:
I acknowledge that these articles are not as specific as I would like, and I would like to see replications of this experiment to show that this method is truly effective. I will share if I find more information in the future.
