In the titration of HCl with NaOH, what is true at the equivalence point?
A.Moles of H⁺ equal moles of OH⁻
B.The pH is always 7
C.The indicator has just been added
D.All liquid has evaporated
Explanation
Core Concept
The equivalence point delivers exactly matching amounts of acid and base per the reaction's stoichiometry. For 1:1 HCl/NaOH, moles of H⁺ supplied equal moles of OH⁻ supplied.
Correct Answer
AMoles of H⁺ equal moles of OH⁻
