Calculate the ph of the solutions obtained by mixing:
a) 50.0 cm3 of 0.25 m ch3cooh and 62.5 cm3 of 0.20 m nach3coo
b) 40.0 cm3 of 0.5 m nh4oh and60 cm3 of 1.0 m nh4cl
c) v cm3 of 0.1 m nah2po4 and 3v cm3 of 0.1 m na2hpo4 (it is actually v not a typo)
ka (ch3cooh) = 1.73 x 10^-5 ; kb (nh3) = 1.8 x 10^-5 ; ka2 (h3po4) = 6.2 x 10^-8
