Question
What is chemically happening when the equivalence point is reached during titration?Question 11Select one:a.moles of hydronium ion = grams of hydroxide ionb.volume of hydronium ion = volume of hydroxide ionc.moles of hydronium ion = moles of hydroxide iond.grams of hydronium ion = grams of hydroxide ion
Solution
The correct answer is c. moles of hydronium ion = moles of hydroxide ion.
During a titration, the equivalence point is reached when the amount of titrant added is exactly enough to neutralize the analyte solution. In the case of an acid-base titration, this means that the moles of hydronium ions (H3O+) from the acid are equal to the moles of hydroxide ions (OH-) from the base. This results in a neutral solution with a pH of 7.
The other options are incorrect because the equivalence point is not about the grams or volume of the ions, but about the moles, which is a measure of the number of particles.
