HA is a monobasic weak acid,
besides H2O molecules, what particles(molecules or ions)are present in the aqueous solution?
ANS:H+,HA, A-, OH-
但係H+ 數目咪就係等於 A- 數目囉，點解仲有OH- ?
acid and alkaline

✔ 最佳答案
Don't forget the H2O(l) molecules in the solution.They slightly ionize to give H^+ and OH^- ions.
Therefore, in reality, OH^- is possible to exist in aqueous solution.

除了H2O會水解成H+,OH-
弱酸形成的陰離子(A-)
會水解
A-+H2O--->HA+OH-
形成OH-離子
弱酸形成的陰離子(A-)
會水解
A-+H2O--->HA+OH-
形成OH-離子
