Different types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses. In this experiment an acid-base titration will be used to determine the molar concentration of a sodium hydroxide (NaOH) solution.Acid-base titrations are also called neutralization titrations because the acid reacts with the base to produce salt and water.ifferent types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses.

The mass of one mole of an element or compound is called its molar mass (symbol M). The molar mass of copper is 63.5 g mol -1. The molar mass of sodium hydroxide is 40 g mol -1. There is a quantity that relates to the number of particles in a mass of substance. This quantity is called the amount of substance.
