Answer:
0.000032 mol/l
Explanation:
A solution that has a higher concentration of hydrogen ions than water is known as an acidic solution and basic or alkaline solutions have a lower concentration of hydrogen ions than water.
The nucleus of a hydrogen atom separated from its electron is known as a hydrogen ion.
pH of an acidic solution (n) = 4.50
Hydroxide ion concentration of an acidic solution = [tex]10^{-n}=10^{-4.50}=0.000032\,\,mol\,/\,l[/tex]
