This lesson focuses on acids and alkalis including acidic and alkaline solutions, neutral solutions, indicators and the pH scale, the colors for litmus paper, and a link to a test.

Through interactive puzzles, informational text and video clips, students will investigate the properties of solutions.

Read and learn about strong and weak Arrhenius bases. View the written formula and discover what certain solutions may be dissolved and which molecules can be transferred.

[Free Registration/Login may be required to access all resource tools.] In this module, students will define pH and use the hydrogen or hydroxide ion concentrations to calculate the pH of a solution. They will also differentiate among...

A simple lab activity that allows good data collection on heat of solution.

[Free Registration/Login Required] Determination of the Molarity of an Acid or Base Solution.

Discussion of water as a solvent. Includes material on hydrogen bonds, hydration, hydrophobic effect, acids, basses, and pH.

Use the virtual lab to determine the pKa of a protein then create a buffer solution with a specific concentration ratio of the protein in its protonated/ unprotonated form.

These are slides eight through ten of a set of slides about Chemical reaction in solution. These slides discuss strong and weak electrolytes, acids, bases, and salts.

This simulation introduces buffer solutions.

Young scholars will use citric acid and sodium carbonate solutions to see that adding a base to an acidic solution makes the solution less acidic. Students will then use a base to help them identify which of two acidic solutions is more...

[Free Registration/Login may be required to access all resource tools.] Help distinguish between degrees of dissociation for strong and weak acids and bases, and then define pH and use the hydrogen or hydroxide ion concentrations to...

A lab activity where students will neutralize and acidic solution with a base and a basic solution with an acid by using their knowledge of a red cabbage indicator. This site includes teacher and student instruction for the lab activity...

In this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. They must first calculate the correct volumes of concentrated acid solution and water to mix together to...

Create a buffer solution at a specific pH using a weak acid and its conjugate base.

Using the Virtual Laboratory design, students perform an experiment to determine the concentration of the unknown HCl solution to four significant figures.

This instructional activity will allow learners to perform pH tests that determine if various solutions are acids or bases (cognitive). Students will test common household solutions such as water, vinegar, milk, and orange juice use pH...

Middle schoolers investigate the pH level of household substances by testing a variety of common compounds. Substances are tested with pH strips and placed on the continuum of the pH scale range of 1 to 14. After testing a solution, the...

This virtual lab activity where students perform the method of successive dilutions using HCl, NaOH, a pH meter, and universal indicator solution to help understand the logarithmic nature of the pH scale.

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator....

This page has animated, 3-D graphics that illustrate the dissociation of strong acids and strong bases and the formation of aqueous solutions.

In this advanced simulation, students experiment with changing the ion ratios in solutions and thus the pH. The experiment can be viewed on a macroscopic or microscopic level, or customized.

In this simulation, students learn how changing the concentration of a solution affects the pH level.

Perform virtual lab experiments safely. Pour and mix specific amounts of various solutions on screen and observe changes in temperature and pH. Choose glassware and other tools (ie. bunsen burner, scale) to assist with virtual lab...
