Zeolites are common minerals found in Earth's crust that play an important role in removing toxic metals and radioactive elements from wastewater. Brookhaven scientists are searching for new materials and techniques to enhance zeolites' ion-exchange reactions.

This lesson will use calcium and iron ions as analogues of more toxic substances. Through double replacement reactions, students will learn how to identify which ion, Ca or Fe, was preferred by the Zeolite. These basic chemical processes and reaction mechanisms can be used on harmful elements like, cesium, cadmium, lead, plutonium.
Vocabulary: atoms, double-replacement reaction, ions, ion exchange, zeolite
|Core Document||Physical Setting/Chemistry Core Curriculum|
|Performance Indicators||KI 1 Scientific Inquiry:|
“The central purpose of scientific inquiry is to develop explanations of natural phenomenon in a continuing, creative process.”
KI 2 Scientific Inquiry:
“Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.”
|Major Understandings||S1.1 Scientific Inquiry:|
“Elaborate on basic scientific and personal explanations of natural phenomenon, and develop extended visual models and mathematical formulations to represent thinking.”
S2.1 Scientific Inquiry:
“Devise ways of making observations to test proposed explanations.
|Performance Indicators||PI 3.2, Physical Setting:|
“Use atomic and molecular models to explain common chemical reactions.”
|Major Understandings||MU 3.2a, Physical Setting:|
“A physical change results in the rearrangement of existing particles in a substance. A chemical change results in the formation of different substances with changed properties.”
MU 3.2b, Physical Setting:
“Types of chemical reactions include synthesis, decomposition, single replacement, and double replacement.”
