Answer :
The pH of the solution containing 3.5×10¯¹¹ M H⁺ is 10.46
What is pH?
This is simply a measure of the acidity / alkalinity of a solution.
The pH measures the hydrogen ion concentration while the pOH measures the hydroxide ion concentration
pH scale
The pH scale is a scale that gives an understanding of the variation of the acidity / alkalinity of a solution.
The scale ranges from 0 to 14 indicating:
- 0 to 6 indicates acid
- 7 indicates neutral
- 8 to 14 indicate basic
Formula for pH
pH = –Log H⁺
Where
- H⁺ is the hydrogen ion concentration
How to determine the pH
- Hydrogen ion concentration [H⁺] = 3.5×10¯¹¹ M
- pH =?
pH = –Log H⁺
pH = –Log 3.5×10¯¹¹
pH = 10.46
Thus, the pH of the solution is 10.46
