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

Stells [14]

Answer:

pH = 9.73

Explanation:

pOH is the negative logarithm of the molar concentration of hydroxide ions 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:

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

$pOH=4.43$

pH and pOH are related by the equation:

$pH+pOH=14$

From which:

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