Question

Arrange the following solutions in increasing order of their pH.
0.1 M NaCl
0.1M CH, NH,Br
0.1M C,H, NH4Cl
0.1M NaF
Use the following data to answer the question:
K, of HF is 6.8*10*, Ko of aniline is 4.3 x 10-10, K, of ethylamine is 6.41*10-4
(A) 0.1M C H, NH,Cl <0.1M CH, NH Br <0.1 M NaCl <0.1M NaF
(B) 0.1M C H NH2Cl <0.1M CH, NH,Br <0.1M NaF <0.1 M NaCl
(C) 0.1M CH3NH2Br <0.1M C HNH,Cl <0.1 M NaCl <0.1M NaF
(D) 0.1M CH, NH Br <0.1M C H NH,C1 <0.1M NaF <0.1 M NaCl
