Sorry that is Incorrect
The correct answer is: A lab that finds the molarity of unknown solutions. The other answer choices are incorrect. Here is why:
- A lab that finds the molarity of unknown solutions.--> This is correct!
- A lab that finds the pH of an unknown solution.--> The lab is focused on finding the molarity of an unknown solution, not the pH. To find the pH, one can use one of the four indicators.
- A lab that finds the [H+] in an unknown solution.--> The lab is focused on finding the molarity of an unknown solution, not the [H+], To find the [H+] one can use the pH and pOH equations.
- A lab that finds the [OH-] in an unknown solution. --> The lab is focused on finding the molarity of an unknown solution, not the [OH-], To find the [H+] one can use the pH and pOH equations.
