Titrations
In the following experiment, we are going to learn how to titrate, how to standardize a base, and how to determine the molecular weight of an unknown acid. If the results turn out the way they should, then a successful experiment has been done, and our purpose has been maintained.
There are three types of titrations, which is when we combine a sample of a solution with a reagent solution of unknown concentration. The three types are acid-base, precipitation, and oxidation-reduction reactions. However, in this experiment only acid-base reactions are dealt with. Acid have a pH from zero to seven, and they ionize in aqueous solutions to give hydrogen ions. Bases have a pH from 7 to 14 and they accept hydrogen atoms. Standardizing a base means making it neutral by adding an acid. The point at which the solution is neutral is called the equivalence point. Dyes which are acid base indicators are used in titrations in order for us to observe the color changes...
