![**Titration of Hydrochloric Acid with Calcium Hydroxide**
An aqueous solution of **hydrochloric acid** is standardized by titration with a **0.116 M** solution of **calcium hydroxide**.
If **20.7 mL** of base is required to neutralize **22.9 mL** of the acid, what is the molarity of the hydrochloric acid solution?
[___] M hydrochloric acid
**Explanation for Students:**
In this experiment, you need to determine the molarity of hydrochloric acid by titration method using a known concentration of calcium hydroxide as the titrant. Note the volumes of the acid and base, as well as the molarity of the base provided.
**Key Concepts:**
- **Titration** is an analytical technique where a solution of known concentration (titrant) is used to determine the concentration of an unknown solution (analyte).
- **Molarity (M)** is a measure of the concentration of a solute in a solution, in terms of amount of substance in a given volume.
- The reaction between hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)₂) is a neutralization reaction, typically producing water and a salt. Use stoichiometry to find the molarity of hydrochloric acid.
This exercise helps demonstrate practical applications of neutralization and molarity calculations in chemistry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7bc30bfd-54a4-45be-8be6-a7bac17a47af%2F8aefce57-7fa3-4c81-a6ac-e051d3d401d5%2Faafrwld_processed.png&w=3840&q=75)
