Please explain in detail.
Dear Student,
(a) lead iodide forms yellow precipitate hence it is not reversible
(b) Silver chloride forms thick white cloud precipitate which cannot be reversed
(c) Once sodium reacts with water hydrogen gas is evolved (escapes) hence little hard to reverse the reaction but under special condition it can be reversed (not feasible)
(d) the potassium ion and sodium suspends in solution as both the molecules are weak base its been difficult to form precipitates hence it can be easily reversed since K+ and Na+ in suspended state.
Answer is Option (d)
Regards.
