Calculate the concentration of HNO3 in a solution at 25°C that has pH (a) 2.06, (b) 1.77, and (c) 6.01.
(a)

Interpretation:
The concentration of
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 concentration of
Answer to Problem 8PPA
Answer
