Students identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

For this chemistry worksheet, students examine the given concept in order to apply in the laboratory setting. The sheet includes in depth background information.

Young scholars investigate the characteristics of the beach environment and explore beach zonation. After gathering samples from different areas of the beach, students discuss how the beaches work and the characteristic of each zone....

In this kinetic energy worksheet, students solve six problems including finding work, determining kinetic energy, finding the coefficient of kinetic friction and finding work done on objects by air resistance and friction.

Learn about weak acid and base ionization reactions and the related equilibrium constants, Ka and Kb. Relate Ka and Kb to pH, and calculate percent dissociation.

Through a variety of activities, students learn that not all acid and base reactions go to completion, and instead, they establish equilibrium. Acid-base equilibrium expressions have their own constants, ka and kb. Students will perform...

Click the basic questions regarding acids, bases, and pH to view the answers. There are sections on basic concepts, buffer solutions, pH calculation, equilibrium constants, indicators, neutralization reactions, and titrations.

This site from the Rensselaer Polytechnic Institute provides an introduction to chemical equilibrium, covering equilibrium expressions, the pH scale, and presenting how to plot log concentration diagrams.

Learn about what happens when a weak acid is added to water. View examples, an acid dissociation constant table, and a study sheet.

Learn where acids and bases fall on the pH scale and the correlation between hydrogen and hydroxide ions. See many examples of how to calculate the pH of a substance. Also find links to the chemistry textbook and tutorials.

A collection of video lectures from a general chemistry course taught at the University of California, Berkeley. The course teaches periodic table, chemical bonds, molecular shape, phase changes, chemical reactions, stoichiometry,...
