Example #5: Equal volumes of a pH = 4.0 and a pH = 6.0 solutions are mixed. What is the pH of the mixed solution that results? The first solution is the more general solution, which MUST be used if the volumes are different. Solution #2 is a shorter calculation that works only if the volumes are equal. Solution #1:
Question: 45.0 mL of 0.650 M HNO3 is titrated by 0.650 M KOH. A) Calculate the pH of the acid solution before any titrant is added. pH = B) Calculate the pH after 1.47 mL of 0.650 M KOH is added to 45.0 mL of 0.650 M HNO3. pH = C) Calculate the pH after 45.00 mL of 0.650 M KOH is added to 45.0 mL of 0.650 M HNO3. pH = D) Calculate the pH after 89.5 mL of 0.650 M This online calculator calculates pH of the solution given solute formula and solution molarity. The solute is assumed to be either strong acid or strong base. All online calculators Articles Suggest a Calculate. Calculation precision. Digits after the decimal point: 3 The pH calculator tool provides expected pH values for a variety of common laboratory and industrial chemicals. Find expected pH for a given concentration simply by entering the molarity or enter weight and total volume. You can even calculate the impact of dilution, entering starting molarity and final volume. 6yfF.
