Chapter 12 Acid-Base Titrations

7

What is the pH at equivalence in a Strong Acid Strong Base titration?

pKa or pKb

What is pH half way to equivalence point for a strong acid/base titrating a weak acid/base

completeness of the reaction between analyte and titrant, as well as concentration of analyte and titrant

What factors effect endpoint sharpness in an acid base titration?

Reactions with this type of titrant are more complete and produce sharper end points in titrant graphs

Why are standard reagents for neutralization titration, generally strong acid or base?

as a buffer equation

When you’re trying to find pH of a weak acid or a base at the stage where analyte has some HA and some OH (before equivalence), how would you solve for pH?

Kb

If a weak acid is at equivalence, what K value do you use to get pH

Theres only conjugate base

Why use Kb when finding pH of a weak acid at equivalence, note: all mol of HA and OH have reacted, so whats on the product side?

No

Is pH of the neutralization of a weak acid/base with a strong acid/base titrant at pH of 7?

Solve for moles of H and OH in reaction

How can you infer if titration has yet to reach equivalence or has passed equivalence?

Try to solve for a concentration of OH by using Ksp equation

If you have yet to reach equivalence of a weak base titration, how would you find pH?

Concentration of conjugate base of weak acid (Kb)

Say, at the equivalence of a weak acid/ strong base titration, what will determine pH?

Acid base indicator

Weak organic acid or weak organic base whose unassociated form differs in color from its conjugate base or its conjugate acid form
