Acid And Bases Equilibrium

Question 1

Volume of titrant needed to reach equivalence point

Answer 1

Moles of acid equal moles of base

Question 2

Ph after addition of some titrant

Answer 2

HA and A- present

Do ice table HA + OH- = A- + h2o

Question 3

Volume of titrant at half neutralization point

Answer 3

1/2 of volume of equivalence point

Question 4

Ph at equivalence point

Answer 4

All HA goes to A-
So Kb equilibrium

Find concentration of A- = miles of A / total volume

Do ice table - A- + H2o= HA + OH-

Find concentration of OH-

Find Ph from 14- POH

Question 5

Excess of beyond equivalence

Answer 5

Find the excess mols of Oh-
Find concentration of Oh- = mols/total volume
Find the POH then 14- POH is PH

Question 6

Before adding titrant

Answer 6

Do usual ice table in h2o
