Description

Is it really gold? Students discover how alloys are
formed and determine what alloy (zinc and copper)
is an attractive replication of gold. With a single
displacement redox reaction, students observe
sodium zincate formed from elemental zinc. Using the
unbalanced equation, students write the oxidation
and reduction half reactions and balance the equation
to complete the experiment. Developed by Jessica
Lyons, this kit includes materials for 50 reactions and
instructions. Grades 11–12.
