Name: ____________________________________________ Date: _____________________ Measuring pH of Common Substances Data Sheet You have 10 cups with different substances. First, predict the pH value of each substance. Next, test each substance with litmus paper. Remember: Acids turn the litmus paper red and bases turn the litmus paper blue. Calculate the average pH. Indicate whether the substance is an acid or base. Substance Predict the pH pH1 pH2 pH3 Average pH Acid or Base? Vinegar Lemon Juice Tomato/Apple Juice Distilled Water Salt Water Turn over for more Î Calculating Averages Example: If pH1 = 5, pH2 = 6 and pH3 = 5, then, the average pH = (5 + 6 +5) ÷ 3 = 16 ÷ 3 = 5.3 MITES 8Day Day14:- Electrical Chemicaland andComputer Biomolecular Engineering MITES8: Engineering Air Pollution: Lesson 6, Acid (and Base) Rainbows ActivityENGINEERING — MeasuringCHALLENGE pH of Common Substances Data Sheet ENGINEERINGCHALLENGE 1 Name: ____________________________________________ Date: _____________________ Measuring pH of Common Substances Data Sheet, continued Substance Predict the pH pH1 pH2 pH3 Average pH Acid or Base?
