Calculate the pH of 100.0 mL of a 0.150M aqueous solution of HNO3

PH scale is used to determine how acidic, neutral or basic a solution is.

pH can be calculated using the following equation

pH = - log[H⁺]

HNO₃ is a strong acid therefore completely dissociates into its ions as follows

HNO₃ - - > H⁺ + NO₃⁻

1 mol of HNO₃ dissociates to produce 1 mol of H⁺ ions

Therefore [HNO₃] = [H⁺]

[H⁺] = 0.150 M

since concentration has been given, its not necessary to consider the volume as concentration is constant throughout the whole solution

pH = - log (0.150 M)

pH = 0.82

the pH of solution is 0.82
