8. NH4^+ (aq) + H2O(l) ------------> NH3(aq) + H3O^+ (aq)
b.HCO3^- (aq) + H2O(l) ------------> H2CO3(aq) + OH^- (aq)
9.
a.Na2SO4 is neutral
b. KF is basic
c. FeBr3 is acidic
10.
H3BO3(aq) ------------> H^+ (aq) + H2BO3^- (aq)
I 0.077 0 0
C -x +x +x
E 0.077-x +x +x
Ka = [H^+][H2BO3^-]/[H3BO3]
5.4*10^-10 = x*x/(0.077-x)
5.4*10^-10*(0.077-x) = x^2
x = 6.45*10^-6
[H^+] = x = 6.45*10^-6M
PH = -log[H^+]
= -log(6.45*10^-6)
= 5.2
11.
Ag2CO3(s) ------------> 2Ag^+ (aq) + CO3^2- (aq)
Ksp = [Ag^+]^2[CO3^2-]
