For a very dilute aqueous solution of `H_(3)PO_(3)` van't Hoff factor

For a very dilute aqueous solution of K_(4)[Fe(CN)_(6)] , van't Hoff factor is

The van't Hoff factor for a very dilute aqueous solution of KAg(CN)_(2) is

An aqueous solution of 0.01 M CH_(3) COOH has van't Hoff factor 1.01 . If pH = - "log"[H^(+)] , pH of 0.01 M CH_(3)COOH solution would be :

If BaCl_(2) ionizes to an extent of 80% in aqueous solution,the value of van't Hoff factor is

K_(2)HgI_(4) is 55% ionized in aqueous solution. The value of Van't Hoff factor is

K_(2)HgI_(4) is 55% ionized in aqueous solution. The value of Van't Hoff factor is
