Options
- A. 4.699
- B. 3.301
- C. 5.401
- D. 3.725
Answer
B. 3.301
Step-by-step solution
The pH of a solution is given by the negative logarithm of the hydrogen ion concentration: pH = - [ H ^+] Given [ H ^+] = 5 10^ -4 \ M pH = - (5 10^ -4 ) pH = -( 5 + 10^ -4 ) pH = -( 5 - 4) pH = 4 - 5 Using the value 5 0.699: pH = 4 - 0.699 = 3.301 Answer: 3.301
