Acids, Bases, and Buffers

Chemistry or physical science fledglings get comfortable identifying acids and bases with a variety of pH indicators. They discover that different indicator solutions have different ranges, practice testing soil acidity, and use antacids...

Keep it simple with this chemistry assignment. Learners examine an acid-base titration graph and answer four questions about the data. Then they will balance neutralization equations and calculate molarity for several specific solutions....

Across the top of the page is a large Z diagram representing varying degrees of acid-base equilibria. Advanced chemistry classes answer eight questions using the values listed for the H+ and the OH- ions that are part of the diagram and...

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...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun resource. Engage them...

In this buffer solution worksheet, students experiment with the addition of different solutions to a buffer solution and observe the changes in pH using a pH probe. Students describe the differences among the addition of pure water and...

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

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 level,...

High schoolers determine the concentration of an acid using titration. In this acid-base titration lesson plan, students determine the concentration of an unknown hydrochloric acid solution using phenolphthalein as an indicator and a...

Buffers don't just magically appear in the stockroom when you need them! Give learners a crash course in buffer basics using an interactive lab assignment. Individuals are tasked with creating a buffer with a certain pH that will react...
