If [H3O^ + ]=1.7*10^ -3 M what is the pOH of the solution?​

The pOH of the solution is 11.23.

Explanation:

To solve this problem, we must remember the following formula for pH: pH = -log[H+].

If we plug in the value we are given, we can find the pH.

pH = -log[H+]

pH = -log(1.7*10^-3)

pH = 2.77

To find the pOH, we use the following formula:

pH + pOH = 14

To solve, we should plug in the value we found above for pH and solve for the pOH.

2.77 + pOH = 14

pOH = 11.23

Therefore, the correct answer is 11.23.

Hope this helps!
