Buffers are solutions that resist a change in pH. In this activity, students will add HCl dropwise to a measured amount of water, monitoring the pH. Students then repeat the process, using a simple buffer prepared by combining baking...

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...

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

An exercise to design a buffer solution with specific properties.

Students explore the chemistry behind the causes and effects of acid mine drainage on a modeled river. In this activity, students examine the chemistry of acidic mine runoff and its effects on river water.

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.

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.

Explains the role of carbonic acid in the blood as part of a buffer system. Includes reactions.

This site gives an indepth look at blood buffering and pH.

Learn about the solvent properties of water, pH, pKa and buffering capacity with a series of problems. The correct answers for the multiple choices problems are reinforced with a brief explanation and the incorrect answers are linked to...

This is a good informational site about Alkalinity. It gives a good explanation of it and some examples.
