Formation of hydroxy‐Al (HA) and hydroxy‐aluminosilicate (HAS) ions was studied in solutions of A1C13, orthosilicic acid and NaOH. Evidence for incorporation of Si into HA is that HA retarded the development of silicomolybdate colour and Si was retained by a cation‐exchanger. The reaction is believed to be mainly a condensation reaction between the hydroxyl groups in Al–OH–Al and Si–OH groups. The HAS with Si/Al ratio 0.3–0.6 showed infrared spectra similar to allophane‐like constituents in Ando soils.
