Calculate the concentration of hydronium in a solution that contains 5.5x10-5 M OH- at 25C. Indentify the solution as acidic, basic, or neutral.

pH = 9.74

The solution is basic

Explanation:

To find the pH of the solution, we need to find the pOH of the solution.

From the question, the concentration of OH^- = 5.5x10^-5 M

pOH = - Log[OH^-]

pOH = - Log 5.5x10^-5

pOH = 4.26

Recall,

pH + pOH = 14

pH = 14 — pOH

pH = 14 — 4.26

pH = 9.74

Since the pH is above 7, the solution is alkaline ie basic

idk what the question is about

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
