Answer:
3.5
Step-by-step explanation:
Given : the hydronium ion concentration is [tex]3.4*10^{-4}[/tex] in orange juice
To Find: what is the pH?
Solution :
Definition of pH : pH is the negative log of the molar hydrogen ion concentration
Formula of pH : - log [H+]
Since we are given H+ = [tex]3.4*10^{-4}[/tex]
So, substituting this value in formula :
[tex]pH = - log [3.4*10^{-4}][/tex]
[tex]pH = - log [3.4*0.0001][/tex]
[tex]pH = - log [0.00034][/tex]
[tex]pH = 3.468[/tex]
pH = 3.468≈3.5
Thus the pH is 3.5
