Question

Analyze the pH of each salt solution: NaC2H3O2, NH4I, KHCrO4.

For KHCrO4 Ka1=1.5X10^-4, Ka2=1.0X10^-9

How do I do this without the Ka values for NaC2H3O2 and NH4I?

Example:

NaHCO3 Na+ HCO3 GP1A cation cónj. base of weak diprotic acid has ionizable H neutral 14 K, 1.0×10-14 5.6x10".' K, = an a 4.3x107 = 2.4x10-5 > K basic basic NH&NO2 2nase of NH4 NO2 conj. acid of weak base conj. base of weak acid acidic basic K, 1.0×10-14 1.8x10-5 ~ 1.0×10-14 4.0x10 14 = 5.6×10-10 = 2.5×10-11 > acidic
