Answer: 13.08
Step-by-step explanation:
To find the pH of a solution, you must use 2 equations:
- pOH= -log [OH], (brackets [ ] mean molarity)
- 14= pH + pOH
First, solve for pOH. You have been given the molarity of OH, so simply use your calculator to find -log(0.12)
Next, solve for pH. Plug in the answer you got from solving -log(0.12). Subtract both sides by that value to find the pH.
You answer should ≈13.08
