The “Elephant Toothpaste” experiment is a very popular, albeit messy chemistry demonstration. To carry out this experiment, place a 250 mL graduated cylinder on something that you wouldn’t mind getting messy.
Types of Chemical Reactions

I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.
Relative Reactivity of Alkali Metals: Lithium with Water
The reaction between lithium and water is shown.
Relative Reactivity of Alkali Metals: Sodium with Water
The reaction between sodium and water is shown.
Relative Reactivity of Alkali Metals: Potassium with Water
The reaction between potassium and water is shown.
Precipitation reaction of potassium chromate and lead(II) nitrate
Yellow potassium chromate solution is added to colorless lead(II) nitrate solution.
Precipitation reaction of potassium chromate and sodium nitrate
Yellow potassium chromate solution is added to colorless sodium nitrate solution.
Precipitation reaction of sodium sulfate and barium nitrate
Colorless sodium sulfate solution is added to colorless barium nitrate solution.
Precipitation reaction of sodium chloride and silver nitrate
Colorless sodium chloride solution is added to colorless silver nitrate solution.
