Question

What is the poh of a 4.5x10^-3 m oh- solution?

Answer 1

The formula for pOH is -log(M)

So, all we need to do is plug in that number! -log(4.5x10^-3)
That gives us 2.3, so the pOH is 2.3 :)

Answer 2

Answer: The pOh of the given solution is 2.35

Step-by-step explanation:

pOH is defined as the negative logarithm of hydroxide ion concentration present in a solution. The equation used to represent pOH of the solution follows:

`pOH=-\log[OH^-]`

We are given:

`[OH^-]=4.5* 10^(-3)M`

Putting values in above equation, we get:

`pOH=-\log(4.5* 10^(-3))`

`pOH=2.35`

Hence, pOH of the given solution is 2.35
