- Determine an unknown concentration or volume using an acid-base titration. Calculate the volume of 0.114 M calcium hydroxide required to neutralize 19.4 mL of a 0.240 M nitric acid solution. mL Alpha-numeric input field Check & Submit Answer Show Approach It is often important to have an accurate concentration of an acid or base solution. With standardization, another type of acid-bas titration, the concentration of an acid or base is determined accurately by the use of either a primary standard or another solution w concentration has already been determined. A primary standard is an acid or base that can be obtained in a very pure form, such a potassium hydrogen phthalate, KHC;H4O4 (often abbreviated KHP), or sodium carbonate, Na2 CO3. The steps involved in standardization calculations are very similar to other acid-base titration calculations, as shown in the following example. tv A hulu W 四)arrow_forwardWrite the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pKa [HA] pH = = 4.352 || pH = 4.874 Answer Bank [A] + log Using the equation to calculate the quotient [A¯]/[HA] at three different pH values.
