Soil Buffering

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...

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...

Titrations are a great work-out routine; you get buffer. But what are buffers and where do they naturally occur? Watch this explanation to find out. Also included are a discussion of acid rain, carbonate buffering,...

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...

Define buffers and their compositions, and learn about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. See an experiment using indicators to showcase just how awesome buffers are. [10:51]

Students examine the social and scientific implications of acid rain. For this acid rain lesson plan, students read an article about acid rain, the causes of acid rain, the effects of acid rain on the environment and the proposals to...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

In this episode created of Crash Course, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions, talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a...

Break down an explanation of diprotic acids for your young chemists with this short instructional video. Using the example of hydrogen sulfide, Paul Groves demonstrates how to calculate the concentration of different products...
