1.If 30.7 mL of a 0.84 M NaOh solution
is added to a 46.1 mL sample of a 0.84 M weak
acid, , HA what is the pH of the resulting solution?
(Ka=1.8*10^-5)
2.What is the pH of a buffer solution that
is 0.13 M propionic acid
and 0.46 M sodium
propionate? Ka(propionic acid)=1.3 *10^-5
3.What is the pH of a solution that is
0.17 M KOCN and 0.10 M
HOCN (cyanic acid)? ( ka for HOCN is 3.5*10^-4 .)
pH =
