Interpretation Introduction To determine: The pH (power of hydrogen) of the solution in which HCl has been dissolved. Explanation In the given problem, 224 mL measured volume of HCl at 27.2°C of temperature and an atmospheric pressure of 1.02 atm is dissolved in an aqueous solution of 1.5 liters. In order to calculate the pH of the corresponding solution, the molarity, which is also equal to the hydronium ion in the given case, is to be calculated. Furthermore, in order to calculate the molarity of the solution, number of moles of HCl is needed to be calculated first. The number of moles of HCl can be calculated applying the ideal gas equation, as mentioned below: P V = n R T In the above equation, P refers to pressure and its value is equal to 1.02 atm, V refers to volume and its value is equal to 0.224 L, n refers to the number of moles, R is the gas constant whose value is equal to 0.0821 L ⋅ a t m m o l ⋅ K , and T refers to temperature for which the value is 27.2°C or 300.3 K. Further, substituting the values in the equation mentioned above: n = P V R T = 1
