![### pH at Equivalence Point in Titration
**Question:** What is the pH at the equivalence point when Jeremiah titrates NaOH with HClO₃?
The reaction involved is:
\[ \text{HClO}_3 + \text{NaOH} \rightarrow \text{NaClO}_3 + \text{H}_2\text{O} \]
To find the pH at equivalence:
\[ \text{pH} = \boxed{?} \]
**Interactive Response:**
Students can enter their calculated pH value in the provided text box and click "Enter" to submit their answer.
---
**Explanation:**
When NaOH, a strong base, is titrated with HClO₃, a strong acid, the reaction goes to completion, producing sodium chlorate (NaClO₃) and water (H₂O). At the equivalence point, the amounts of acid and base are stoichiometrically equal, and the solution mainly contains the salt of the strong acid and base. The pH of the solution at this point is determined by the neutral nature of the salt, resulting in a pH close to 7.
**Diagrams/Graphs:**
There are no diagrams or graphs present in this example. The focus here is on the chemical equation and the calculation based on titration principles.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8eb77797-9ac9-400b-9a5e-2bcfb6c77ad3%2F246acc9e-1329-416f-99e5-1894781e5800%2F6fbr3hm_processed.jpeg&w=3840&q=75)
