## Summary of Experiment No(1) Prepared by student: Enas muhammed ### Titration of the neutralization reaction between hydrochloric acid and sodium hydroxide solution #### **Objective of calibration:** A solution of unknown molarity of sodium hydroxide using a solution of hydroxide. #### **Tools:** * Burette * Pipette * Guide #### **Experience:** The buret, in which hydrochloric acid with a known standard is placed. The burette is filled to zero, and it is called the initial reading. Ten milliliters of sodium hydroxide is taken with a pipette and placed in the titration flask. "The titration flask is washed with water and distilled water," then the indicator (phenolphthalein) is added, then a little distilled water is added. The beginning of the titration is drop by drop of HCL with continuous shaking until the color disappears completely until the last drop. When the color disappears, the calibration has been completed, after which readings are taken and shown on the table: the initial reading, the final reading, and the difference between them. Then the experiment is repeated again at least two or three times. In the second experiment, the end of reading in the first experiment is the beginning of reading in the second experiment, then the calibration is repeated with the same steps as the first experiment and applied to the second experiment, and so on.
