Answer:
[H₃O⁺] = 3.162 × 10⁻⁹ moles / liter
Explanation:
The pH is calculated with the formula:
pH = -lg[H₃O⁺]
From here the concentration of hydronium ion (H₃O⁺) will be:
[H₃O⁺] = [tex]10^{-pH}[/tex]
[H₃O⁺] = [tex]10^{-8.5}[/tex]
[H₃O⁺] = 3.162 × 10⁻⁹ moles / liter
Answer:
3.17 x 10^-9
Explanation:
log 3.17 =.5 log 10^-9 =-9 .5+-9=-8.5 =pH 8.5
