Example 4

easy
Is a solution with pH = 12 acidic, neutral, or basic?

Solution

  1. 1
    pH > 7 indicates a basic solution.
  2. 2
    pH = 12 is strongly basic (high concentration of OH−\text{OH}^- ions).

Answer

Basic (pH = 12 > 7)\text{Basic (pH = 12 > 7)}
The pH scale runs from 0 to 14, with 7 being neutral. Values above 7 are basic and below 7 are acidic.

About Base

A substance that accepts H+\text{H}^+ ions (protons) or donates OH−\text{OH}^- ions when dissolved in solution, raising the pH above 7.
