What is the pH when 30.0 mL of 0.10 M HCOOH solution is titrated with 8.6 mL of 0.20 M NaOH? (Ka = 1.8 x 10^-4) Given that Kb for (CH3)2NH is 5.4\times0-4 at 25C, what is the value of Ka for (CH3)2NH2 at 25 C? What is the Kb for the followin...
If 20 mL of 0.10 M NaOH is added to 45 mL of 0.20 M HC2H3O2, what is the pH of the resulting solution at 25 degrees Celsius? (Ka = 1.8 x 10-5) If 50.00 mL of 1.00 M HC_2H_3O_2 (K_a = 1.8 times 10^{-5}) ...
with this kind of equation i am working with my Ka should be NaCl/[HCl][NaOH]. but my Ka should look like this: Ka = [H+][A-]/[HA]. in the equation above i don't even know where to put my calculated hydronium value. i am so lost. basically my overall question is: how do...
