Question

The method used to determine the equivalence point of an acid-base solution is called:

A) activation
B) titration
C) precipitation
D) salting out

Answer 1

Answer: Option (B) is the correct answer.

Step-by-step explanation:

A technique or method used to determine the concentration of an unknown solution is measure by using a solution of known concentration is known as titration.

Equivalence point is the point where the moles of standard solution (titrant) is able to neutralize the moles of solution of unknown concentration.

Activation energy is defined as the minimum amount of energy required to initiate a chemical reaction.

Precipitation is defined as the chemical reaction in which two solutions upon chemically reacting to each other result in the formation of solid insoluble substance.

Therefore, we can conclude that the method used to determine the equivalence point of an acid-base solution is called titration.

Answer 2

Answer is: B) titration.

Equivalence point is the point in which there is stoichiometrically equivalent amounts of acid and base.

Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.

The midpoint of a steep vertical section indicates the equivalence point
