Question

What is the [H+] in a solution with pOH of 0.253?

Answer 1

pH + pOH = 14

pH + 0.253 = 14

pH = 14 - 0.253

pH = 13.747

[ H+] = 10 ^ -pH

[ H+ ] = 10 ^- 13.747

[ H+ ] = 1.790x10⁻¹⁴ M

hope this helps!

Answer 2

Answer: pOH of the solution is 13.41.

Explanation:-

pH is the measure of acidity or alkalinity. It is also defined as negative logarithm of hydrogen ion concentration.

`pH=-log[H^+]`

`pOH=-log[OH^-]`

`pH+pOH=14`

Given:
`[H^+]` = 0.253

Thus
`pH=-log[0.253]`

`pH=0.59`

`0.59+pOH=14`

`pOH=14-0.59=13.41`
