Question

In an acidic solution, [OH-] ___________ [H+].

Option 1: =
Option 2: <
Option 3: >
Option 4: higher

Answer 1

In an acidic solution, the concentration of hydronium ions ([H3O+]) is greater than the concentration of hydroxide ions ([OH-]). Acidic solutions have pH values less than 7, while basic solutions have pH values greater than 7.

Step-by-step explanation:

In an acidic solution, the concentration of hydronium ions ([H3O+]) is greater than the concentration of hydroxide ions ([OH-]).

Acidic solutions have pH values less than 7, indicating a high concentration of H3O+ ions. On the other hand, basic solutions have pH values greater than 7, indicating a low concentration of H3O+ ions and a high concentration of OH- ions.

For example, if the concentration of [H3O+] is 2.0 x 10-3 M, the solution is acidic because it is greater than 1 x 10-7 M, while the concentration of [OH-] is less than 1 x 10-7 M.
