What is the poH of a
4.5 x 10-3 M OH solution?

2.35

Explanation:

pOH is the negative logarithm of hydroxide ion concentration in a solution. Mathematically, pOH is expressed as pOH = -log(OH-)

where (OH-) is the concentration of hydroxide ion.

So, pOH calculations are as follows

pOH = - log(4.5 x 10-3 M)

pOH = - (-2.3468)

pOH = 2.3468 (The minus signs cancelled out)

Then, round pOH value to the nearest hundredth: pOH is 2.35

Thus, the poH of a 4.5 x 10-3 M OH solution is 2.35
