A collection of grid puzzles that cover topics in basic chemistry, including acids, salts, alkalis, chemistry lab equipment, the periodic table, states of matter, and more. These are excellent for topic review and reinforcement. The...

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...

A virtual lab where students determine the concentration of acetic acid in vinegar using a 0.110 M NaOH standard solution and an acid-base indicator, phenolphthalein.

A hands-on science experiment where students test acidity levels by using red cabbage extract and learn the acid levels of known and unknown liquids.

Engaging hands-on science lessons for grades 2-6 on chemical and physical changes.

Conduct a series of virtual experiments using basic, acidic and neutral household liquids. Draw a conclusion from the results collected in an online lab journal.

Guidelines for a simple lab demonstration using phenolphthalein, a chemical that changes color depending on whether it is in the presence of an acid or base.

This resource presents a collection of simple science experiments kids can do using household materials. The procedures include diagrams and are simple to follow.

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

In this lab, students are scientists from the Department of Agriculture and presented with the problem that a farmer has brought to them. The farmer believes the problems are due to illegal dumping of PCB's and other chemicals that...

Did you know that chemistry can be found in your kitchen? Enter this amazing virtual world where your first stop is to the kitchen. Locate the clues and move on to the Lab Journal where you can test each item in two experiments: Cabbage...

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...

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 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 student...

The equivalent is the amount of a substance which will either react or supply with one mole of hydrogen ions and acid-base reactions or do the same with one mole of electrons in a redox reaction.

An exercise to design a buffer solution with specific properties.
