Textbook-style strong acid and base problems that can be checked using the Virtual Lab.

Textbook-style weak acid and base problems that can be checked using the Virtual Lab.

Listen and learn as you discover definitions for acid, base, and acid-base reaction. View example formulas of Arrhenius and Bronsted-Lowry acid and bases.

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.

In this experiment, you will explore the behavior of the monoprotic acid (acetic acid) and the polyprotic acid (phosphoric acid). By titrating, you will examine the acid and conjugate base species present across the pH scale and the...

Learn about the relationship between Ka of a weak acid and Kb for its conjugate base. Practice equations for converting between Ka and Kb, and converting between pKa and pKb.

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

Beginning with the example of the hydrangea, this page gives a good overview of acid-base chemistry.

Understand the definition of Bronsted-Lowry acids and bases, strong and weak acids and bases, and how to identify conjugate acid-base pairs.

This simulation uses solutions of weak acids and examines the response of this equilibrium system to the addition of the corresponding conjugate base.

This page, created by a chemistry professor from the University of Waterloo, provides an introduction to conjugate acid-base pairs.

This site, created by a University of Waterloo Chemistry professor, applies conjugate pair theory. It also deals with the ionization constants for acids and bases.

The objective of this article is to introduce conjugate pairs as a way to relate acids and bases.

This simulation allows the study of the pH of buffer solutions. Six acid-base conjugate pairs are available, and the concentration of the acid and of the base can be adjusted over one order of magnitude.

This tutorial describes how buffers protect against pH changes when strong acid or base is added.

Perform an experiment to determine the concentrations of a mixture of two acids.

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.

Students examine equilibrium and buffer solutions in a biological setting.

Perform an experiment to determine the pKa and concentration of an unknown acid.

This tutorial presents a review of the definitions for pH and buffer solutions

This site is designed to be a supplement for students of organic chemistry. Its tutorials and self-grading tests are interactive and extremely helpful.

This simulation introduces buffer solutions.

Great practice for reviewing the subjunctive and indicative tenses. Determine which verb tense to use in a sentence based on the tense that is used in the main clause. Choose the present or past subjunctive form, or the present,...

This virtual laboratory demonstrates how an enzyme-linked immunosorbent assay (ELISA) is carried out and some of the key experimental problems that may be encountered. Students will learn about the assay procedure and the equipment and...
