Question

The [H3O+] of a solution is 1*10^-8. This solution has a pH of

Answer 1

The pH of a solution with a [H3O+] of 1 x 10^-8 M is 8, indicating that the solution is basic.

Step-by-step explanation:

Given that the [H3O+] of a solution is 1 x 10^-8 M, we can find the pH by taking the negative logarithm (base 10) of the hydrogen ion concentration:

pH = -log[H3O+]

pH = -log(1 x 10^-8)

pH = 8

This implies that the solution has a pH of 8, and since the pH is above 7, the solution is basic in nature.

Answer 2

pH = 6

Step-by-step explanation:

Given data:

Concentration of H₃O⁺ = 1 ×10⁻⁸ M

pH of solution = ?

Solution:

pOH = -log [H₃O⁺]

pOH = -log [1 ×10⁻⁸ ]

pOH = 8

pH + pOH = 14

pH = 14 - pOH

pH = 14 - 8

pH = 6
