Product Description

By: John Wass
Western Branch H.S., Chesapeake, VA

Acids are acidic, bases are basic, and salts are neutral—right? Not exactly! Teach your students that certain salts dissolve in water to produce acid solutions and others produce basic solutions. Using universal indicator in Petri dishes displayed on the overhead projector, show your students a colorful pH rainbow-made from the simple hydrolysis of salts. Write and discuss the hydrolysis reactions for five different salts with water. A table of acid-base properties of common cations and anions in aqueous solutions is provided for your convenience. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.
Concepts: Acids and bases, pH, hydrolysis of salts.
Time Required: 10 minutes
Chemicals Provided: Aluminum chloride hexahydrate, ammonium chloride, sodium bicarbonate, sodium chloride, sodium phosphate, universal indicator solution, five overhead dishes, and stirrers.
Note: An overhead projector is recommended for this demonstration.
