抱歉沒有解答
真的不太會連續迫近法
謝謝大家

B. [4 pts) Calculate the pH of a 0.02 M H₂A solution.
If this H₂A with Kaf100 and Kaz= 4.0 x 10-²
-5
C. (5 pts) Calculate the [H*] in 2.0 x 10¹5 M HA, if this
HA with K₂ = 4 x 10-6.
[Successive approximation should be needed).
Q 3, B. [show calculation).
Consider a weak acid HA with a Ką value of 4 x
10-6. Calculate the pH of a solution that contains
4.0 x 10-6 M HA and 4.0 x 10-6 M NaA.
[Successive approximation should be needed).
Show your Successive approximation
