N2  - The aquation stoioheiometry of cis. and trans-Cr(NH3),(OH2)Br2+ and cis- and trans-Cr(NH3)4(OH2)I2+ ions when either spontaneous, Hg2+ promoted, or carried out via the hydroxo forms generated in basic solution has been examined. The two latter treatments have been conducted on cis-Cr(NH3)4(OH2)C12+ ion. Spectrophotometric methods show all lose halide with retention of configuration. The rates of aquation in acid media of the Cr(NH3)4(OH2)Br2+ and Cr(NH3),(OH2)I2+ ions have been investigated and comparisons are made with related tetraammine and bis(ethylenediamine) oomplexes.   Evidence has accumulated to show almost complete stereoretentivity in the aquation reactions of chromium(111) amine complexes.
