How can you determine which compound is a stronger acid/base if
neither compound is a strong acid or a strong base? Chapter 16,
question 45 c. in chemistry a molecular approach textbook
In the following acid–base reaction, classify each substance as
the stronger acid, weaker acid, stronger base, or weaker base. HCN
+HCO3- ---> <--- CN- + H2CO3. Which direction does
equilibrium favor? a) to the left b) both directions c) to the
right
calculate the pH for a strong acid + strong base titration in
which 5.00 mL of the M(OH)2 was transferred via pipet to
a beaker and HCl was added from the buret.
Concentration of base is 0.0721 M
Concentration of acid is 0.0524 M
Please show work.
Calculate the pH:
a) before any HCl is added
b) after the addition of 4.00 mL HCl
c) after the addition of 9.00 mL HCl
d) 4.00 mL beyond the equivalence point
Calculate pH for a strong acid/strong base titration.
Determine the pH during the titration of 39.8
mL of 0.334 M HI by
0.334 M KOH at the following
points:
(a) Before the addition of any KOH-?
(b) After the addition of 19.9 mL of
KOH-?
(c) At the equivalence point-?
(d) After adding 47.8 mL of
KOH-?
1) How do the effects of a small amount of strong acid or strong
base on water vs those on a buffer differ? Explain what happens on
a molecular level in a diluted buffer, undiluted buffer and water
solution when a small amount of strong acid or base is added.
2)Explain the term buffer capacity and what observations would
indicate that the buffer capacity has been exceeded,
how does titration of a strong monoprotic acid with a strong
base differ from a titration for a weak monoprotic acid with a
strong base with respect to the following a) quantity of base
required to reach the equivalance point b) ph at the beginning of
the titration c) ph at the equivalance point d) ph after addition
of a slight access of base e) choice of indicator for determining
the equivalence point
