Assertion : Silver chloride dissolves in execss ammonia.
Reason : `AgCl` forms a soluble complex, `[Ag (NH_(3))_(2)] Cl` with ammonia.

Silver chloride dissolves in excess ammonia due to the formation of a soluble compplex whose formula is

(A) White precipitate of silver chloride gets dissolved in NH_(4)OH solution. (R ) NH_(3) reacts with AgCl to form a soluble complex with formula [Ag(NH_(3))_(2)]Cl .

Assertion : Cu(OH))_(2) is soluble in NH_(4)OH but not in NaOH . Reason : Cu(OH)_(2) forms a soluble complex with NH_(3) .

Assertion : Cu(OH))_(2) is soluble in NH_(4)OH but not in NaOH . Reason : Cu(OH)_(2) forms a soluble complex with NH_(3) .
