Answer:
pH = 5
Explanation:
We are given;
- Concentration of a solution HI as 0.00001 M
We are required to calculate the pH of Hydronium ions.
- When the acid dissociates in water to;
HI + H₂O → H₃O⁺(aq) + I⁻(aq)
- The concentration of H₃O⁺ ions is 0.00001 M\
- We need to know that pH = -log[H₃O⁺]
Therefore;
pH =-log 0.00001 M
= 5
Thus, the pH of the hydronium ions is 5
