Match the point during an acid-base titration with the description of how the pH would be determined at that point. 1.) After titrant is added but before the equivalence point 2.)At the equivalence point 3.)After the equivalence point 4.) Before titrant is added Match with: A.)pH of salt formed during the reaction B.)pH with excess titrant C.)pH with original concentration of analyte D.)pH of remaining analyte
The titration shown in the plot has an equivalence point at pH = 3.2. Identify which of the indicators would be appropriate for 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...
