Options
- A. 3.5229
- B. 4.229
- C. 3.229
- D. 3.5223
Answer
A. 3.5229
Step-by-step solution
The pH of solution A is given as 4. [ H ^+]_A = 10^ -4 M For solution B, the hydrogen ion concentration is three times that of solution A. [ H ^+]_B = 3 [ H ^+]_A = 3 10^ -4 M pH of solution B = - [ H ^+]_B pH = - (3 10^ -4 ) pH = 4 - 3 Using 3 = 0.4771: pH = 4 - 0.4771 = 3.5229 Answer: 3.5229
