Solution
The equivalence point in a titration is reached when the amount of titrant added is enough to completely neutralize the analyte solution. The chemical reaction is complete at this point.
In terms of the options you've provided:
a. The volume of H3O+ does not necessarily equal the volume of OH-. The volumes of the reactants do not necessarily have to be equal for the reaction to reach the equivalence point.
b. The grams of H3O+ do not necessarily equal the grams of OH-. The mass of the reactants does not necessarily have to be equal for the reaction to reach the equivalence point.
c. The moles of H3O+ equal the moles of OH-. This is the correct answer. At the equivalence point, the number of moles of acid (which donates H3O+ ions) equals the number of moles of base (which donates OH- ions). This is because the definition of the equivalence point is when the moles of acid equal the moles of base, resulting in a neutral solution.
d. The grams of H3O+ do not necessarily equal the moles of OH-. The units are not the same on both sides of the equation, so they cannot be equal.
