Answer:
The answer to your question is pH = 1.93, acid.
Step-by-step explanation:
Data
[OH⁻] = 8.6 x 10⁻¹³
pH = ?
Process
pH measures the [H⁺] concentration. The pH scale goes from 0 to 14. If the pH of a solution goes from 0 to 6.9 the solution is acidic, it the pH = 7.0, the solution is neutral or if the pH is between 7.1 and 14 the solution is basic.
1.- Calculate the pOH
pOH = -log [OH⁻]
-Substitution
pOH = -log[8.6 x10⁻¹³]
pOH = 12.06
2.- Calculate the pH
pH + pOH = 14
-Solve for pH
pH = 14 - pOH
-Substitution
pH = 14 - 12.06
-Result
pH = 1.93
3.- Conclusion
This solution is an acid.
