A weak base, B has a dissociation constant of 3.17X10^-5 mol dm^-3 at 25 degree celsius.
(i) write an equation for hydrolysis of B.
(ii) In what volumes should 0.05 moldm^-3 of HCl acid and 0.05 moldm^-3 of B be mixed to make 1dm^3 of buffer at PH 9.2?
(iii) the above buffer is diluted by adding 100cm^3 of distilled water at 25 degree celsius. Determine the pH of the resulting buffer.
): im stuck at the second part..
