Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Calculate pH by using the pH to H⁺ formula: These flasks range in size from 10 mL to 2000 mL and are carefully calibrated to a single volume. On the narrow stem is a calibration mark. The precise mass of solute is dissolved in a bit of the solvent, and this is added to the flask. Then, enough solvent is added to the flask until the level reaches the calibration mark. Question 1 Calculate the pH of a 1.0 × 10−6M solution of HNO3 Question 2 Calculate the pH of a 1.0 × 10−1M solution of NaOH This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. pH Calculation Formula. The formula to calculate pH is: pH = -log [H+] The brackets [] refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may be given concentration in other units. To calculate pH, first convert concentration to molarity. Science. Chemistry. Chemistry questions and answers. Calculate the pH of 100.00mL of 0.20 M HNO3 solution after 43.00 mL of NaOH 0.20 M have been added. How would I be able to calculate the pH of a buffer that includes a polyprotic acid and its conjugate base? For example, if I were to add a certain amount of the polyprotic acid H2A and a certain amount of its conj base A^2- (obviously in the form of a salt, say Na2A), how would I find the pH? Assume I know the ka1 and ka2 values. Now what? .
