chemical equations- the Ka and Henderson Hasselbalch equation - Please help, I'm really stuck on the following:-
A weak acid has a PKa of 7.713. Calculate the pH of a solution in which the ratio of the concentrations of undissociated acid to acid anion ([HA]/ ...
Calculate the value of Kb - The [OH-] = 1.3 x 10^ -6 M for a 0.025 M solution of a weak base. Calculate the value of Kb for this weak base.
a) 5.2 x 10 ^ -5
b) 3.1 x 10 ^ -7
c) 7.7 x 10 ^ -9
d) 4.0 x 10 ^ -8
e) 6.8 x 10 ^ ...
