公式

## How to Calculate [OH-] from pOH ### Formula **[OH-] = 10^(-pOH)**

计算示例

Find [OH-] for pOH = 2.

  1. 01[OH-] = 10^(-2)
  2. 02[OH-] = 0.01 M
  3. 03pH = 14 - 2 = 12

常见问题

What is [OH-]?

The molar concentration of hydroxide ions in solution. Higher [OH-] means more basic.

How do I get pOH from pH?

pOH = 14 - pH at 25 C.

What is [OH-] in pure water?

10^-7 M at 25 C, the same as [H+].
