The molarity of an unknown acid will be determined using a method is called “titration”. Titration is a
procedure involving the carefully measured and controlled addition of a solution from a buret into a
measured volume of a sample solution. A buret is a glass tube with a tap at the end, and it is known for
delivering the volume of a liquid.
In this experiment, the purpose of the concentration of acetic acid lab
is to determine the concentration of acetic acid in vinegar .The indicator and the phenolphthalein was
added at the end of the titration, the indicator is when the colour changes at a certain pH value, and
phenolphthalein is a common indicator that changes its colour a 7 pH for the strong acids and bases.
Titration is a technique that can be used to determine the unknown acid of a solution. In this case, an
unknown concentration, meaning the amount of dissolved acid can be used in the concentration for the
hydroxide base. This chemical reaction is called neutralization, in which means that the acids and the
bases react in water to make salt and the water. We can also use the indicator, which changes colour at a
certain pH scale. The reason why we can use the indicator, so that we can determine if the chemical
reaction has been fully neutralized.
