This demonstration makes a white precipitate by mixing equal amounts of silver nitrate and potassium chloride:
AgNO3 (aq) + KCl (aq) → KNO3 (aq) + AgCl (s)
- 0.2M AgNO3
- 0.2M KCl
- small beaker
- disposable pipets
1. Add a few mL of silver nitrate to the beaker
2. Add a few mL of potassium chloride to the beaker
This is a great one for students to do.
Safety goggles should be worn at all times.
This lesson plan‘s topic is the Evidences of Chemical Reactions. Students learn the various evidences, then they get a change to practice identifying them with a hands on activity. Colorless to White is used in the activity portion of this lesson.
