[化學] About titration question
The titration of 100.0 mL of a 0.100 M solution of weak acid H3A with
0.200 M NaOH is carried out. What are the major species (except water) at
each of the following specified points in the titration?
A) HA2-, after 100.0 mL NaOH is added
B) H2A- and HA2-, after 40.0 mL NaOH is added
C) HA2- and A3-, after 120.0 mL NaOH is added
D) HA2-, after 50.0 mL NaOH is added
E) H2A- and HA2-, after 85.0 mL NaOH is added
F) none of the above
我的問題是這樣子
H3A -> H2A- -> HA2- > A3-
0 50 ? ?
就是我不知怎麼算HA2-是100 A3-是150
希望有神手可以替我解答 感恩
