Sour and Bitter: Acids and Bases

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

Investigating pH is intriguing, especially with these activities designed for an introductory chemistry or physical science class. Pupils use litmus paper to distinguish acids and bases and then make indicators from food products....

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

Everyone's familiar with acids like vinegar and lemon juice—but what makes them different from ammonia and baking soda? Science sleuths discover acid base theory using a video from JFR Science. Viewers explore the interactions of acids...

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

Students learn about acids, bases, and pH levels as they interact with the various features of this simulation.

Students investigate the pH of various solutions with indicators. For this acids, bases and indicators lesson plan, students use a variety of indicators to test solutions for their pH. Students determine which indicators are the best to...

Looking for a comprehensive plan for teaching acid-base chemistry? Science scholars discover acid-base interactions through a thoughtfully written unit. The resource is divided into paced activities and individual work designed to...

[Free Registration/Login may be required to access all resource tools.] In this module, define acids and bases and distinguish between Arrhenius and Bronsted-Lowry definitions to predict products in acid-base reactions that form water.

This resource must have a greater concentration of hydroxide ions than hydrogen ions because it makes pH seem basic. The video describes what happens on a molecular level to change the pH of a liquid and focuses on the importance of...
