Textbook Question
Chapter 11.3, Problem 129E
pH The pH of a chemical solution is given by the formula
pH = −log[H+]
where [H+] is the concentration of hydrogen ions in moles per liter. Values of pH range from 0 to 14. A solution whose pH is 7 is considered neutral. The pH of pure water at 25 degrees Celsius is 7. A solution whose pH is less than 7 is considered acidic, while a solution whose pH is greater than 7 is considered basic.
- a. What is the pH of household ammonia for which [H+] is 10−12? Is ammonia basic or acidic?
- b. What is the pH of black coffee for which [H+] is 10−5? Is black coffee basic or acidic?
- c. What is the pH of lemon juice for which [H+] is 10−2? Is lemon juice basic or acidic?
- d. What is the concentration of hydrogen ions in human blood (pH = 7.4)?
