molybdenum bromide is dissolved in water and lead nitrate added only one third of halogens is precipitated

Yes, Molybdenum (II) Bromide is a high water-soluble and lead nitrate

Explanation:

Molybdenum (II) Bromide is a high water-soluble, crystalline form of molybdenum for use consistent with bromides and lower (acid) pH. Metallic bromides are traded under the trade name AE Bromides™. For some applications of crystal production, most metal bromide compounds remain water-soluble as used in water treatment, chemical division, and ultra-high purity. Bromide can be measured using the addition of carbon disulfide (CS2) and chlorine in an aqueous solution.
