Product Details

Because of its beautiful multicolored compounds, vanadium, atomic number 23, was named after the Scandinavian Goddess of Beauty, Vanadis. In this demonstration, a yellow vanadate solution goes through a series of color changes when shaken together with granulated zinc. Each color change is due to a change in the oxidation state of the vanadium. Vanadium truly lives up to its name in this demonstration! Teacher Demonstration Notes included.

Concepts: Oxidation–reduction, properties of vanadium.
Time Required: 20 minutes

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
