Have students complete the Introduction to Water Chemistry lesson before conducting this activity. The pigment in red cabbage that causes the red color change is called flavin an anthocyanin. Flavin is a water-soluble pigment also found in apple skins, plums and grapes. Very acidic solutions turn the indicator a red color, neutral solutions turn the indicator a purple color, and basic solutions turn the indicator a greenish-yellow color. At a lower pH, more hydrogen ions are in solution, and therefore the solution is acidic.

The Many Phases Of Water | 5th Grade Science Worksheet | GreatSchools
Many reactions in nature involves an increase or decrease in acidity. For example, as CO2 concentrations in the atmosphere increase, greater amounts are dissolved in the oceans, reacting with H2O to form carbonic acid H2CO3. Environmental and chemical engineers who focus on water quality, water treatment and water remediation need to measure, monitor and sometimes even adjust the pH of water. For example, in the water treatment process, important chemical reactions are affected by the pH of the water. Through today's activity, we will learn more about the pH of different liquids. For each group, label eight paper cups: milk, water, baking soda, Windex, soda pop, lemon juice, vinegar, cabbage indicator.

Hand out the worksheets. Direct student groups to each pour a small amount from the "cabbage indicator" cup into the seven cups of different liquids and a powder. Add just enough indicator until a color change appears. Then have students use pH-indicator strips to measure and record the pH of the liquids in each cup. Have students complete the worksheet questions. Conclude by leading a class discussion to compare results and conclusions, and make the connection to real-world applications, as described in the Assessment section. Focus the conversation on topics such as acid rain and acid mine drainage. Have students predict which test liquids they think are acidic and which are basic. Observe their written observations, data and answers to gauge their comprehension. What's Going On?

Why or why not? Make sure everyone understands the answers. How did your results from the red cabbage pH indicator compare to the pH indicator strips? Listen to student experiences; answers will vary. From most acidic to most basic, the pH values of the tested items are: lemon juice [2], vinegar [3], soda pop [4], milk [6], pure water [7, neutral], baking soda [9], Windex [11, an ammonia solution]. What other acids and bases do we encounter every day? Listen to student ideas. Example everyday bases: Egg whites [8], antacids [], soapy water [12], bleach [13], oven cleaner [13], liquid drain cleaner [14]. Oven cleaners are designed to have pH values greater than 12 because the grease, fat and carbon found in ovens are easily dissolved in reaction with extremely alkaline [base] solutions.

A range of pH values are found in the human body from highly acidic gastric acids [1] to skin [5. See if students want to extend the activity by testing other items of interest. Why is understanding the pH value of liquids important to environmental engineers? Points to make: Human activity can disturb the natural balance necessary for ecosystems to work. Engineers are focused on preventing and fixing situations that put our natural environment at risk, for example, by the alteration of pH levels from the misuse and overuse of natural resources—acid mine drainage, industrial waste, leaking sewage and fuel tanks, agricultural chemical runoff, dissolved pharmaceuticals, etc.

Talk about acid neutralization remediation using bases and make the connection to what students learned in the lab. Engineers also need to know about pH to design tools such as the pH indicator strips. You've heard of "acid rain. Answer: The pH of water is generally neutral [7], and rainwater is slightly acidic [], but acid rain is much more acid [] and thus, corrosive. This is not the natural pH of rainwater and it alters the environment for wildlife, trees and plants, and slowly deteriorates buildings and statues. With increasing acidity, water begins to cause harm and destruction of ecosystems, such as slowing the reproduction of fish and other marine life and being too acidic to survive, or dissolving the minerals such as calcium carbonate that form the shells of mollusks. From what you know now, what would happen if we mixed some of our solutions? If time remains, have students mix solutions they found to be acidic with solutions that they found to be basic to observe any chemical reactions and corresponding color changes.

Or, add baking soda to the acidic solutions to neutralize them. Troubleshooting Tips Double up on the paper cup with the Windex; otherwise, it tends to leak after a few minutes. Consider testing items found in the kitchen, bathroom, laundry and garden. Activity Scaling For lower grades, conduct the similar Acid and Base Rainbows activity, targeted for sixth grade students. For upper grades, go into more depth with the definition of pH. Especially if students have had some experience with logarithms in mathematics and ions in chemistry, define pH as a measure of the activity of hydrogen ions. Once students have completed the worksheet, have them manipulate this equation to solve for the concentration.

Sixty-five percent of a human's body is water. Water is crucial for life. It has three forms. The solid form is ice. The liquid form is water. The gas form is steam. Water becomes less dense when it is heated. When water is cooled, it becomes denser and forms into ice. Water's solid form, ice, can float on its liquid form. The reason is that water molecules are more tightly packed in its liquid state than in its solid state, ice.
