Ka for NH4+ is 5.7 x 10-10 B. Calculate the pH change that takes place when a 100-mL portion of 0.005M HCl is added to 400 mL of the buffer solution described in part (a) (a) Calculate the pH of a solution that is 0.200M NH3 and 0.300M in NH4Cl.

Higher is the Ka value, stronger the acid. (a) Ka of NH4+ = 5.6×10^(-10) (b) Ka of HOCl = 3.5×10^(-8) (c) Ka of HC2H3O2 = 1.8×10^(-5) (d) Ka of HF = 7.2×10^(-4) Order of Ka:- HF > HC2H3O2 > HOCl > NH4+ So, the order of strength of acid:- HF > …View the full answer

What is the pH of a 0.10 M solution of NH4F? The Ka of NH4+ is 5.6*10^-10 and the Ka of HF is 6.8*10^-4. Answer according to professor is 6.21, but not sure how. I already know NH4+ alone would be 5.12.
