When 23.3 mL of 0.14 M HCl are added to 50.0 mL of a 0.16 M solution of a weak monoprotic base, the pH of the solution is 10.50. What is the Kb of the weak base?
do u find moles of both and then add the moles for HB+ and then just use the B- moles for the B on the henderson hasselbach equation
and then solve for Ka and then solve for Kb?
i don't get the right answer
