A titration curve is a graphical representation of the pH of a solution during a titration. The figure below shows two different examples of a strong acid-strong base titration curve. On the left is a titration in which the base is added to the acid and so the pH progresses from low to high.
The correct answer to this open question is the following.
A graphical representation of the strength of an acid or base is the "pH scale."
The pH scale is used to represent the acidic grade of a solution. The ph scale helps us to identify the concentration of hydrogen ions in any solution. The first studies on the subject were developed by Danish scientist Soren Lauritz Sorensen in 1909.
B) on a regular basis over a long period time This provides data about the average temperature, rainfall, windspeed, etc. to accumulate enough information
