2. Objectives:
The objective of this laboratory exercise is to determine the molarity of hydrochloric acid in the given sample.
To learn lab skills to prepare and dilute a standard solution; to find the strength of an acid or a basic solution.

3. Apparatus: 50mL burette. 5mL volumetric pipette. 0.1M NaOH.
Hydrochloric acid.
Phenolphthalein indicator.
Burette stand.
Two 250mL Erlenmeyer flask.
Wash bottle filled with distilled water.
Funnel.

4. First: add hydrochloric acid in a conical flask using the pipette.

5. Second: add a couple of drops from phenolphthalein indicator.

6. Third: add hydroxide solution using burette
Third: add hydroxide solution using burette. (Add until the color stays pink)

7. Fourth: Repeat what you did again.

8. Fifth: Do your calculations..
V1 is the volume of hydrochloric acid.
V2 is the average volume which is the two volumes/2.
m1 is already known (0.1 M)
And now you have to find m2
m1v1=m2v2

9. Summary From this experiment we have learned that:
acids turn the color of phenolphthalein indicator into pink.
sour to taste.
and reacts with OH-.
