Question

Simple acid base titration using phenolphthalein full theory

Answer 1

Answer:

Titration is used for determining how much of an analyte in moles (or millilmoles) is in a solution. Analyte is the term for the dissolved unknown in the titration experiment. This is done by slowly adding a standard solution, or a reagent of known concentration, until the titration is determine to be complete.

Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and red in basic solutions.

Phenolphthalein is added to the known volume of the acid solution in a conical flask.  Then, NaOH is added slowly in drops to the mixture until the solution becomes pale pink in colour.

Then, the reading of the Naoh left is taken and used to compute the molarities.
