Given a solution with a hydroxide ion concentration, oh=3.73×10^-5,what is the ph

Stells [14]

Answer:

<em><u>pH </u></em><u>= 9.73</u>

<u></u>

Explanation:

<em>pOH</em> is the negative logarithm of the molar <em>concentration</em> of<em> hydroxide ions </em>and pH is the negative logarithm of the concentration of hydronium ions.

The mathematical expression to determine pOH is:

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

Where [OH⁻] means the molar concentration of hydroxide ions.

Substituting:

$pOH=-\log {(3.73\times 10^{-5})$

$pOH=4.43$

<em>pH </em>and <em>pOH</em> are related by the equation:

$pH+pOH=14$

From which:

$pH=14-pOH\\\\pH=14 - 4.43\\\\pH=9.57\leftarrow answer$
