  23. 23. Think-Group-Share What does pH show about substances?  What atoms they are made of  Their amount of energy  How acidic or basic they are
  24. 24. Think-Group-Share What does pH show about substances?  What atoms they are made of  Their amount of energy  How acidic or basic they are
  25. 25. What is pH? V. pH shows how acidic or basic a solution is.
  26. 26. Think-Group-Share Match each type of substance with its pH range.  bases a) pH 7  acids b) pH 8 - 14  neutrals c) pH 0 - 6
  27. 27. Think-Group-Share Match each type of substance with its pH range.  bases - b) pH 8 - 14  acids - c) pH 0 - 6  neutrals - a) pH 7
  28. 28. What is pH? B. pH0 - pH6 = acids. Acids = pH0 - pH6
