Choose the statement that is true at the mid-point, or half-equivalence point, in the titration of a monoprotic weak acid and a strong base

A)The moles of conjugate base and weak acid present in the solution are equal.

B)The moles of strong acid and weak base present in the solution are equal.

C)The moles of conjugate base and strong base present in the solution are equal.

D)The moles of strong base and weak acid present in the solution are equal

Expert Solution

The titration is between a monoprotic weak acid and a strong base. At the mid - point of half equivalence point, half of the weak acid is neutralized by the base.

A) The moles of conjugate base and weak acid present in solution are equal Since half of moles of acid are neutralized, the moles of both conjugate base and acid are equal. So this statement is TRUE

B) The moles of strong acid and weak base present in the solution are equal The acid is weak in this solution. So this statement is FALSE.

C) The moles of conjugate base and strong base present in the solution are equal The strong base is completely consumed at the half equivalence point. So this statement is FALSE.

D) The moles of strong base and weak acid present in the solution are equal The strong base is completely consumed at the half equivalence point. So this statement is FALSE.

Hence only statem ent (A) is TRUE.

The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.460 moles of a monoprotic weak acid (Ka = 1.0 × 10-5) is titrated with NaOH, what is the pH of the solution at the half-equivalence point? Calculate the [H ] and pH of a 0.000117 M iodoacetic acid solution. Keep in mind that the Ka of iodoacetic...

Identify the equivalence point on the titration curve shown here. A is the equivalence point B is the equivalence paint C is the equivalence point pH D is the equivalence point Define the end point of a titration. It is the point at which the pH no longer changes. It is when a change that indicates equivalence is observed in the analyte solution. It is a synonym for equivalence point.
