Strong acid-strong base and precipitation titration curves, like other kinds of potentiometric titration curves, inherently possess an inflection point where the slope is a minimum as well as one where it is a maximum. In any kind of titration the first of the inflection points can be caused ...
The first curve shows a strong acid being titrated by a strong base. There is the initial slow rise in pH until the reaction nears the point where just enough base is added to neutralize all the initial acid. This point is called the equivalence point. For a strong acid/base reaction, t...
Strong Acid - Strong Base Titration Curve Determining the Concentration of an Unknown Substance from Titration Determining the pH of the Excess Reactant During Titration Lesson Summary Frequently Asked Questions What happens when you titrate a strong acid with a strong base? If you titrate a strong...
The titration curve for a weak base - strong acid titration is different than that of a weak acid - strong base titration. The curve begins at pH 11 and slopes downward gradually until the equivalence point is reached. At the equivalence point, the curve slopes downward sharply and evens out...
Titration curves Titration of a strong acid ? When a strong acid is titrated with a strong base the pH at any point is determined solely by the concentration of un titrated acid or excess base. ? The conjugated base that is formed has no effect on pH. Titration of a weak acid ? Weak...

The problem that i am running into is that my pH curve does not look like a strong acid / strong base curve should look. I get a very slow and drawn out linear fall. I am also seeing pH value drift if i stop for a while. This tells me that the reaction rate between such dilute...
