Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Performing calculations is for more than just mathematicians — it's an important science skill, too. Demonstrate the pH calculations using the slide show resource. The final resource of a seven-part unit introduces young scientists to...

Across the top of the page is a large Z diagram representing varying degrees of acid-base equilibria. Advanced chemistry classes answer eight questions using the values listed for the H+ and the OH- ions that are part of the...

Acids and bases combine to create our most popular shampoos—who knew?! Using the eighth lesson in a 24-part series, your classes study how acids and bases combine to create safe mixtures such as those in your scholars' shampoos. They...

Young scholars perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.

Students investigate acids, bases,and pH. They test the acidity and basicity of various household items using litmus paper. Using their results, they rank the substances according to pH and identify the contributing chemical on the label.

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

The first two pages provide a chart to complete with results of a lab test using different solutions and indicators. The data analysis questions will help your students understand the concentrations of the solutions and how they affect...

Ninth graders complete an experiment to determine the pH values of a variety of common household substances. They use red cabbage to find the indicator colors of the pH range. They complete a data table that includes a prediction and...

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

There is a chart to complete with results of the titrations for the 14 different pH indicators.  There are also nine questions for data analysis, and then four problems requiring equations, molarities, and pH values.

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

Chemistry stars calculate ion concentrations, pOH, or pH in different solutions. For questions in the latter half of the worksheet, they also have to explain why a solution is acidic, basic, or neutral and solve for molarity of a solute....

Students perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with acids...

Middle schoolers test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.

High schoolers use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.

In this pH worksheet, students are given information and directions as to how to calculate the pH of solutions. They use their calculators to find the pH of given solutions and apply what they learned about identifying acids and bases.

In this acid and base learning exercise, students answer 7 questions about acidic and basic solutions such as the color each turns litmus paper, the pH values, the balanced equations for neutralization reactions and their pH and...

Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

In this addition worksheet, students solve 9 problems in which two digit numbers are added with no regrouping. Students rewrite an addition sentence that is in horizontal format and stack the numbers in a place value chart.

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

Students investigate the strength of acids and bases experimentally. They answer the question, "How can pH be used to determine possible product tampering?" by testing acids and bases with litmus paper.

Students determine the pH level of water and its effect on aquatic plants and brine shrimp eggs. This is a three part instructional activity that leads the student through the development of an understanding of water pH. They form a...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply.
