More Acid-Base Indicators

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

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...

Once I told a chemistry joke, but there was no reaction. A STEM lesson plan using the inquiry method covers the topics of acids and bases. Young chemists find the pH of substances; measure and classify substances; design a question and...

There is a chart to complete with results of the titrations for the 14 different pH indicators.  There are also nine questions for data analysis, and then four problems requiring equations, molarities, and pH values.

Lead the class in a colorful exploration of acids and bases as they learn to differentiate between the two. They identify common items considered acidic and basic, then explore their strengths and weaknesses. They titer solutions 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...

The use of acid-base titration as a way to find the mass of oxalic acid is the focus of this chemistry video. Sal takes a sample problem from a chemistry textbook and solves it. The math involved in the process is quite complex.

Seventh graders investigate acids and bases. In this acids and bases lesson plan, 7th graders use household items such as coffee, lemons and soap to define acids and bases. They observe a demonstration to show how indicators determine if...

Students prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test solution...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...
