Calculate the pH of an aqueous solution at 25°C that is (a) 0.035 M in HI, (b) 1.2 × 10−4 M in HNO3, and (c) 6.7 × 10−5 M in HClO4.
(a)
![Check Mark](/static/check-mark.png)
Interpretation:
The pH of the given aqueous solutions at
Concept Information:
Strong acids:
In strong acids, the ionization of acid is complete. This implies that the concentration of the hydrogen ion or hydronium ion will be equal to the initial concentration of the acid at equilibrium.
pH definition:
The concentration of hydrogen ion is measured using
The
On rearranging, the concentration of hydrogen ion
To calculate: The pH of an aqueous solution of 0.035 M
Answer to Problem 16.7WE
Answer
(a)
