As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Suitable for an AP Biology class, the lab found here has teen bioengineers working with plasmids to clone DNA. If you have not done a similar lab, the instructions may be rather difficult to follow. Both the teacher and learner...

In this chemistry learning exercise, students solve twenty five multiple choice problems about a variety of chemistry topics. Students answer questions about equilibrium, solubility, reaction rates, titrations, and entropy.

In this environment worksheet, students answer 6 different questions. The questions are really an activity for each one. This requires extra space to complete them on separate worksheets.

Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...

In this fluids, electrolytes, and acid-bas balance system study questions, students define 12 words associated with this system. They answer 12 short answer questions about the components of the acid-balance system.

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.

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

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

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.

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.

As part of acid rain study, (environmental chemistry lab) students investigate the differences in pH of soil samples. They will collect and dry samples from the local prairie including grassland, transition, forest and riverbank and...

[Free Registration/Login may be required to access all resource tools.] Students begin by predicting whether a salt solution is acidic, basic, or neutral, and then practice writing balanced equations for hydrolysis reactions. They also...

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...

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...
