calculate the pH of a solution of 0.25 M HBrO (kb=3.57*10^-6) Thank you
If Kb=5.6x10^-10, calculate the pH of a solution that is 0.25 M NaCH3C00. (Ans 9.08)
What is the pH of a 0.2 M CH3CH2NH3(BrO) solution? Kb(ethylamine CH3CH2NH2)=4.3 x 10^-4 Ka (HBrO) = 2.3 x 10^-9 The answer is "pH 11", but I keep getting 11.96. (i compared Ka to kb and used Kb since it is bigger) then solved for pH using only Kb. Please explain the correct way of doing it if i was doing it wrong. thanks!
