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
