||What is the [OH-] of a
0.10 M solution of NaCN?
||Calculate the pH of a 0.10 M NaC2H3O2
solution. Ka for HC2H3O2 = 1.8
||Consider a salt, A+B-,
which reacts with water in such a way that both A+ and B-
hydrolyse to give a weak base, AOH and a weak acid BH respectively. Given
that Ka = 1.0 x 10-5 and Kb = 1.0 x 10-10
predict whether the resulting solution would be acidic or basic and explain
||Aspirin is acetylsalicylic acid,
a monoprotic acid whose Ka value is 3.27 X 10-4. Does
a solution of the sodium salt of aspirin in water test acidic, basic, or neutral?
||The Kb value of the oxalate
ion, C2O42-, is 1.85 X 10-10.
Is a solution of K2C2O4 acidic, basic, or
||Consider the following compounds
and suppose that 0.5 M solutions are prepared of each: NaI, KF, (NH4)2SO4,
KCN, HC2H3O2, CsNO3, and KBr.
Write the formulas of those that are (a) acidic, (b) basic, (c) neutral.
||Calculate the pH of 0.15 M Na2SO3.
