In the titration of a solution of weak monoprotic acid with a 0.1275 M solution of NaOH, the pH half way to the equivalence point was 4.48. In the titration of a second solution of the same acid, exactly twice as much of a 0.1275 M solution of NaOH was needed to reach the equivalence point. What was the pH half way to the equivalence point in this titration?

consider the titration of a weak monoprotic acid (HA) with a strong base. If the titration has begun, but the equivalence point has not yet been reached, which of the following is true: A) The solution is a bugger and the HH equation can be used to compute the solution pH B) The excess titrant will dominate and control the pH at this point C) The dissociation of the weak acid to donate protons will determine pH - make a...
The pH at the equivalence point of a titration of an unknown monoprotic substance with a...
The pH at the equivalence point of a titration of an unknown monoprotic substance with a strong titrant is determined to be 6.63. Based on this pH value, explain whether the unknown substance is a strong acid, strong base, weak acid, or weak base. A chemist wants to perform a reaction at pH = 8.3 so they attempt to make a buffered solution. For this buffer, the chemist dissolves 12.5 moles of methylammonium, CH3NH3+, (Ka = 2.3 x 10–11) and...

In the titration of a solution of weak monoprotic acid with a 0.1800 M solution of NaOH, the pH half way to the equivalence point was 4.42 . In the titration of a second solution of the same acid, exactly twice as much of a 0.1800 M solution of NaOH was needed to reach the equivalence point. What was the pH half way to the equivalence point in this titration?

In the titration of a solution of weak monoprotic acid with a 0.1525 M solution of NaOH, the pH half way to the equivalence point was 4.40 . In the titration of a second solution of the same acid, exactly twice as much of a 0.1525 M solution of NaOH was needed to reach the equivalence point. What was the pH half way to the equivalence point in this titration?

To learn about titration types
and how to calculate pH at different points of titration. In an
acid-base titration, a titrant (solution of a base or acid) is
added slowly to an analyte (solution of an acid or base). The
titration is often monitored using a pH meter. A plot of pH as a
function of the volume of titrant added is called a pH titration
curve. Prior to the titration, the pH is determined by the
concentration of the...
