S: Acid and Base Scavenger Hunt

FC: Acid and Base Scavenger Hunt By: Courtney L. and Terra M. 2nd period

1: Acidic Solution Contains more hydrogen ions than hydroxide ions. | Neutral Solution Contains equal concentrations of hydrogen ions and hydroxide ions. | Basic Solution Contains more hydroxide ions than hydrogen ions.

2: pH scales go from 0-14, but in this testing we will only use 1-12. Acid are 0-6 and go to the left, bases are 8-14 and they go to the right. Neutral is 7 and is in the middle.

3: Item Predicted Actual Sodium Hydrogen Sulfate 1 1 Lemon Juice 2 2 Cranberry Juice 3 3 Coke 5 4 Black Coffee 5 5 Soapy Water 7 6 MIlk 8 7 Baking Soda 6 8 Glass Cleaner 5 9 Bleach 1 10 Pet Zer-Odor Spray 10 11 Ammonia 11 12

4: Materials Needed 1. Ammonia 2. Lemon Juice 3. Cranberry Juice 4. Milk 5. Coke 6. Black Coffee 7. Baking Soda 8. Glass Cleaner 9. Soapy Water 10. Pet Zer-Odor Spray 11. Sodium Hydrogen Sulfate- which you can get from any chemistry set 12. Bleach 1. Small measuring cup- 1 ounce 2. Filter 3. Coffee maker 4. Coffee grounds 5. Small Glass Cup 6. Spoon

5: 1.Predict the pH for each item you will test. 2.Get a piece of paper and make a table with 3 columns with 12 spaces. One will be for the items you will test. One for the predicted pH and one for the actual pH. 3.Gather all materials listed above, which will be needed for testing. 4.Set up appropriate testing area, clear and make sure to have some towels nearby for spills that may occur. 5.Measure 5 mL of soap and pour in small glass, and then fill the cup about halfway with water. Stir the spoon to mix the soap and water for about 15 seconds or until the mixture looks mixed together. 6.Take the pH strip and carefully dip the tip into the liquid. 7.Use the pH scale you were given to determine the pH level, take the strip and match it as closely to a color you can. 8.Record the number in the pH actual level column in your table. 9.Take a picture, have the product along with the pH scale and the pH strip on the right pH level. 10.Wash the testing materials, such as the measuring cup, spoon and throw away the used pH strip

6: 11.Get the next item, Lemon Juice and measure 5 mL of Lemon Juice. 12.Dip the tip of the pH strip into the Lemon Juice. 13.Use the scale to determine the pH level and then record the pH level in the table. 14.Take a picture of the product, pH strip, and pH scale. 15.Wash the measuring cup with soap and water and dispose of the used pH strip. 16.Get the next item Bleach and measure 5 mL of Bleach. 17.Dip the pH strip into the Bleach 18.Quickly take a picture of the product, pH strip, and pH scale because the Bleach will bleach the strip white very quickly. 19.Record the pH level in the table, then wash the used measuring cup with soap and water and dispose of the used pH strip. 20.Get the next item, Ammonia and measure 5 mL of the liquid. 21.Dip the pH strip in to the liquid 22.Match the Strip with the right color on the scale and record the pH level in the table. 23.Take a picture of the product, pH strip and scale.

7: 24.Wash the measuring cup with soap and water and dispose of the used pH strip. 25.Get the next item, Milk, and measure 5 mL of the liquid. 26.Dip the pH strip into the liquid and match the strip to the right pH level on the scale. 27.Take a picture of the product, pH strip and pH Scale. 28.Wash the measuring cup with soap and water and dispose of the used pH strip. 29.Get the next item, Coke, and measure 5 mL of the liquid. 30.Dip the pH strip in to the liquid and match the correct color on the pH scale. 31.Record the pH level in the table and then take a picture of the product, pH strip, and pH scale. 32.Wash the measuring cup with soap and water, and dispose of the used pH strip in the trash. 33.Get the next item, Glass Cleaner, and measure 5 mL of the liquid. 34.Dip the pH strip in to the liquid and match it to the correct color on the pH scale.

8: 35.Record the pH level in the table and take the picture of the product, pH strip, and pH scale. 36.Wash the measuring cup with soap and water and dispose of the used pH strip in the trash. 37.Take the Coffee filter and put it in the coffee maker, pour the coffee grounds in and then get a cup of water and pour it where belongs. Let the coffee brew, once its brewed measure 5mL of black coffee in to the measuring cup. 38.Dip the pH strip into the coffee and match the pH strip with the correct color on the pH scale. 39.Record the pH level on the table and take the picture of the product, pH strip, and pH Scale. 40.Wash the measuring cup, clean out the coffee maker and dispose of the used pH strip and also the used coffee grounds and filter. 41.Get a small glass cup and fill it halfway with water, then measure 5 mL of baking soda and pour into the water. Mix with spoon until Baking Soda dissolved into water. 42.Dip the pH strip into the liquid and then match it to the correct level on the pH scale.

9: 43.Record the pH level in the table and take a picture of the product, pH strip, and pH scale. 44.Wash the measuring cup, small glass cup and dispose of the used pH strip in the trash. 45.Get the next item, Pet Odor Spray, and measure 5 mL of the liquid. 46.Dip the pH strip into the liquid and match it the correct level on the pH scale. 47.Record the pH level on the table and take the picture of the product, pH strip and pH scale. 48.Wash the measuring cup and dispose of the used pH strip in the trash. 49.Get a small glass cup halfway full of water and then measure 5 mL of Sodium Hydrogen Sulfate and pour into the water. Stir with a spoon to mix the crystals until they dissolve into the water. 50.Dip the pH strip into the liquid and then match the pH strip to the correct pH level on the scale. 51.Record the pH level and take a picture of the product, pH strip, and pH scale. 52.Wash the measuring cup, spoon, and small glass cup, then dispose of the used pH strip in the trash.

10: 53.Get the next item, Cranberry Juice, and measure 5 mL of the liquid. 54.Dip the pH strip into the liquid and match to the correct pH level on the scale. 55.Record the pH in the table and take the picture of the product, pH strip, and pH scale. 56.Wash the measuring cup and dispose of the used pH strip. 57.Put everything back where it came from, and clean up any mess made.
