ON CHLORONIUM SALTS.

Herschel/HIFI discovery of interstellar chloronium (H2Cl+) ***

We report the first detection of chloronium, H2Cl, in the interstellar medium, using the HIFI instrument aboard the Herschel Space Observatory. The 212−101 lines of ortho-H35 2 Cl and ortho-H37 2 Cl are detected in absorption towards NGC 6334I, and the 111−000 transition of para-H35 2 Cl is detected in absorption towards NGC 6334I and Sgr B2(S). The H2Cl column densities are compared to those o...

Missing salts on early Mars

[1] Our understanding of the role of water on Mars has been profoundly influenced over the past several years by the detection of widespread aqueous alteration minerals. Clay minerals are found throughout ancient Noachian terrains and sulfate salts are abundant in younger Hesperian terrains, but these phases are rarely found together in the early Martian rock record. Full alteration assemblages...

Evaporative Salts from Saline Lakes on Tibet Plateau: an Analog for Salts on Mars,

Martian salts: Salts have been identified on Mars by spectrometers on orbiters and rovers. Among them, Mg-, Ca-, and Fesulfates were identified or implied in Meridiani outcrop [1] and in Gusev salty soils and rocks [2,3]; kieserite (MgSO4.H2O) and “polyhydrated sulfates” were found in Valley Marineris, Meridiani Planum, and gypsum (CaSO4.2H2O) near North Pole [4,5,6,7]. Recently, chloride-beari...

Effects of some salts and acids on citrus leaf abscission

Effects of Soluble Salts on Insoluble Phosphates.’

This study has been taken up from two viewpoints. First, a study of field and pot experiments, with a view of determining, if possible, the indirect action of various salts when used as fertilizers; to ascertain if the increase in yield obtained from the use of a fertilizer is not due in part to the solvent action which it exerts on the comparatively insoluble phosphorus in the soil. Second, to...
