Classroom Resources: Acids & Bases
1 – 11 of 11 Classroom Resources
-
Observations, Chemical Change, pH, Acid Base Reactions, Chemical Change | High School, Middle School
Lab: How do Sinkholes Form?
In this lab students will learn how acidic groundwater reacts with limestone, causing it to erode. Sinkholes form when eroded limestone underneath the surface of the earth can no longer support the ground above it. Students will test how acid reacts with a variety of rocks and determine which rocks would be best to build a city on top of in order to reduce the chance of sinkholes forming.

Acid Base Reactions, Stoichiometry, Percent Composition, Titrations, Indicators | High School
Lab: The Egg-straordinary Issue
In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.
-
Acid Base Reactions, Stoichiometry, Limiting Reactant | High School
Lab: Fizzy Drink
In this lab, students will learn the properties of acid and bases while applying the principles of stoichiometry to calculate the amount of base needed to neutralize an acid completely and produce a bubbly drink.
-
Acid Base Reactions, Titrations | High School
Lab: Vinegar Quality Control
In this lab, students will perform a titration of a vinegar sample to determine if it is it close to the concentration claimed on the bottle.
-
Chemical Change, Catalysts, Acid Base Reactions, Combustion | High School
Demonstration: Stop & Go Gases
In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame.
-
Acid Base Reactions, Heat of Neutralization | High School
Lab: Heat of Neutralization
In this lab, students carry out an acid base reaction to calculate the heat of neutralization.
-
pH, Acid Base Reactions, Chemical Change, Acid Rain | High School
Lab: Seeing the Effects of Acid Rain
In this lesson, students will prepare an environment and make acid rain to see how the acid rain effects the items in the environment.
-
Reaction Rate, Reaction Rate, Acid Base Reactions | High School, Middle School
Lab: Plop, Fizz: How to Affect the Rate of a Chemical Reaction
In this lesson, students will react Alka-Seltzer tablets with water. By varying the temperature of the water, particle size of the Alka-Seltzer, and concentration of the Alka-Seltzer they can see the effect on the rate and strength of the chemical reaction.
-
Acid Base Reactions, Indicators | Middle School, Elementary School, High School
Demonstration: Another Secret Message
In this demonstration, students will observe a hidden message while understanding simple acid/base chemistry and indicators.
-
Solubility, Acid Base Reactions, Intermolecular Forces, Titrations, Indicators | High School
Lab: Alka-Seltzer & Gas Solubility
In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.
-
Acid Base Reactions, Limiting Reactant | High School
Lab: Acid/Base Stoichiometry
In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.
