Answer

13.999\text{13.999}

Step-by-step solution

2 steps

To find the pOH when the pH is given, we use the relationship between pH and pOH at 25°C:

pH+pOH=14\text{pH} + \text{pOH} = 14
  1. Substitute the given pH value into the equation.

    We are given pH=0.001\text{pH} = 0.001.

    0.001+pOH=140.001 + \text{pOH} = 14
  2. Solve for pOH.

    Subtract 0.001 from both sides of the equation:

    pOH=14−0.001\text{pOH} = 14 - 0.001 pOH=13.999\text{pOH} = 13.999

    The pOH is 13.999\text{13.999}.
