Select the correct order of solubility of AgCN(s) at 25^(@)C. Given that at this temperature its solubility is S_(1)(in presence of 1 M AgNO_(3)) , S_(2)(in presence of 1 M NH_(3) (aq)), S_(3)(in presence of pure water) and S_(4)(in presence of 1.5 M KCN).

Answer»

`S_(1) lt S_(2) lt S_(3) lt S_(4)`
`S_(1) lt S_(4) lt S_(2) lt S_(3)`
`S_(4) lt S_(1) lt S_(3) lt S_(2)`
`S_(3) lt S_(4) lt S_(1) lt S_(2)`

SOLUTION :Order of solubility `{:(underset(larr "COMMON ion EFFECT" rarr)(S_(4) lt S_(1)) lt underset(["Pure water"])(S_(3)) lt underset(["reactive ion effect: complex formation"])(S_(2))),((1.5M CN^(-))(1.0M Ag^(+))):}`
