An inorganic compound (A) is a Lewis acid an d light yellow in colour. It fumes in moist air. The intensity of fumes further increase when a rod dipped in NH_(4)OH is brough near it. The aciedic solution of the compound does not give andy precipitate on passing H_(2)S gas. However, it gives a white precipitate on adding NH_(4)OH solution in the presence of NH_(4)Cl and the white precipitate dissovles on adding NaOH in excess. The solutin formed when white precipitate is dissolved in NaOH is of
