Hydrochloric Acid Titration

The aim of the experiment is to find the exact concentration of the hydrochloric acid (HCl) solution by reacting (titrating) it with the standard base sodium hydroxide (NaOH) solution.
Titration is the name of the analytical process that is used to determine the concentration of an unknown solution by reacting it with a standard solution (known concentration). The known concentration solution is called the titrant, and the unknown concentration solution is called the analyte.
The purpose of using HCl and NaOH is because they are strong acid and base, which means they will fully dissociate in water (will separate to ions). This is important because when the reaction reaches the equivalence point H and OH ions will combine together

To do this experiment some particular tools and instruments are needed. The Burette is used to put bace NaOH in it, it has an error of ± 0.1ml. In titration experiment the burette is hanged on holder above the Conical flask. The conical flask has the acid HCl in it, and it is the place where the acid react with the base. The Pipette is the instrument that used to measure the amount of the acid HCl before adding it to the conical flask, it’s error is ± 0.03ml. To put the base in the burette an instrument called Funnel is used. A wash bottle is used as well.

Before the instruments were used they were washed by deionized water. The reason behind cleaning the instruments with deionized water is to assure that they are clean and free of unwanted materials or previous samples that can interact with the samples used in the experiment and interrupt the measurements and results. The deionized water used because it has had all it’s minerals ions removed, and this is important for the aim of cleaning the instruments so no mineral ions will remain in the
