Question

If the [OH-]=8.6*10^-13, what would the pH of this solution be? Would this solution be considered acidic or basic?

Answer 1

Answer:

The answer to your question is pH = 1.93, acid.

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.
