Answer:
pH= 0.368, [OH-] = 2.5 x10^-14
Explanation:
Hydrogen sulfite ion is a weak acid, so we can first find it's pH then convert it into pOH.
The equation to find pH is pH= -log[H+]
therefore; pH= -log(0.429)
pH=0.368
To find pOH we know 14= pH + pOH
therefore; pOH = 14 - pH
14 - 0.368 = 13.6 = pOH
We then know pOH = -log[OH-]
to find [OH-] we can rearrange the equation from about to make
10^-pOH = [OH-]
10^-13.6 = 2.5 x 10^-14
