Answer:
7.4.
Explanation:
∵ pH = -log[H₃O⁺].
∴ pH = -log(2.5 x 10⁻⁷) = 6.6.
<em>∵ pH + pOH = 14.</em>
<em />
∴ pOH = 14.0 - pH = 14.0 - 6.6 = 7.4.
The lithosphere, hydrosphere, and atmosphere are the abiotic parts of the planet.
I believe it is "They have hydroxide ions" because bases are usually made up of hydroxide ions and other element ions.
