Answer #1

HONH3+ is conjugate acid of HONH2

So, its pH would be less than 7

F- is conjugate base of HF

So, its pH would be more than 7

NaNO3 is neutral salt.

So, its pH would be 7

CN- is conjugate base of HCN

So, its pH would be more than 7

CN- is stronger base as compared to F- because Ka of HF is more.

So, pH of CN- will be more than pH of F-

Answer:

HONH3Cl: 1

HF: 3

NaNO3: 2

HCN: 4
