Engage your chemistry students by having them observe precipitate reactions and practice writing the products of a chemical reaction (5 reactions). I chose to select 5 reactions rather than the traditional chart precipitates for the sake of time, fitting it into one period as well as clear equation writing for students.

Objectives:

• Observe and recognize when a precipitate has formed
• Write the products for a chemical reaction

Materials:

0.1M NaCl

0.1MKNO3

0.1M AgNO3

0.1 M NaI

1 M Cu(NO3)2

2  M NaOH

0.1 M Fe(NO3)3

gloves

5 test tubes / pair of students
