Answer to Question #152201 in General Chemistry for RICHARD SITIENEI

Question

Explain briefly the reasons for the following observations supporting your discussion, wherever possible by means of balanced chemical or ionic equations or structures(I)when molybdenum (ii)bromide is dissolved in water and lead nitrate added only one third of the halogens are precipitate?

Answer 1

Molybdenum(II) Bromide is a highly water soluble crystalline Molybdenum source for uses compatible with Bromides and lower (acidic) pH. Metallic Bromides are marketed under the trade name AE Bromides™. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding carbon disulfide (CS2) and chlorine. Molybdenum Bromide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
