B. KOH
C. NH3 (kB = 1.76*10-5)
D. CH3NH2 (kB = 4.4*10-4)
E. Ba(OH)2
Homework Answers
The solution is given below with explanation
![will completely : for NaOH as it is a strong base it dissociates in water PLOH = -log [or] We have given [NaOH] /for] = 0.1om](http://img.homeworklib.com/questions/7e5750c0-df44-11eb-aaf3-4b5f06d0a6fb.png?x-oss-process=image/resize,w_560)
Hence NaOH and KOH will have the highest value of pH which is equal to 13.
Thank you
