The pOH of a solution where the [OH-] is 7.3 x 10-² M is 1.14.

HOW TO CALCULATE pOH.

  • The pOH of a solution can be calculated from the hydroxide ion concentration by using the following formula:

  • pOH = -log[OH-].

  • According to this question, the hydroxide ion concentration (OH-) of a solution is given as: 7.3 x 10-²M. The pOH of the solution can be calculated as follows:

  • pOH = - log {7.3 x 10-²}

  • pOH = 1.14

  • Therefore, the pOH of a solution where the [OH-] is 7.3 x 10-² M is 1.14.
