Question

What is the pOH of a substance with a Hydrogen concentration of 3.45 x 10-9. suppose to be a small 9

Answer 1

Answer:

The correct answer is option d.

Explanation:

Concentration of hydrogen ions = $[H^+}=3.45\times 10^{-9} M$

The pH of the solution is given by :

$pH=-\log[H^+]$

$pH=-\log[3.45\times 10^{-19}]=8.46$

The relation between the pH and pOH is given by :

pH + pOH = 14

pOH = 14 - pH

$pOH=14-8.46=5.54$

The pOH of the substance is 5.54.
