In the group analysis of cations, when we add a
P small amount of solid ammonium chloride

W \( \left(\mathrm{NH}_{4} \mathrm{Cl}\right) \) and an excess of ammonium hydroxide \( \left(\mathrm{NH}_{4} \mathrm{OH}\right) \) solution, A gelatinous white precipitate indicates the presence of-
(1) \( \mathrm{Fe}^{3+} \)
(2) \( \mathrm{Ni}^{2+} \)
(3) \( \mathrm{Al}^{3+} \)
(4) None
