EXPERIMENT 3

LAB REPORT

Submitted By : Mutlu DEMİREL Group: 3

MATERIALS:

0.1 M NaOH , Potassium Hydrogen Phthalate , Desiccator , Phenolphthalein , 5 ml Vineger , Distilled water , Flask , Buret , Erlenmayer Flask

PURPOSE:

In this experiment our aim is to determine the molarity of NaOH and weight percentage of with neutralization titration.

METHOD:

Gravimetric Analysis

THEORY:

Both NaOH and HCl are frequently used reagents: the former an example of a strong base, and the latter an example of a strong acid. This classification comes from the position of the equilibrium when each is placed in an aqueous solution:
