The hydrogen chromate ion may be protonated, with the formation of molecular chromic acid, H 2 CrO 4, but the pK a for the equilibrium H 2 CrO 4 ⇌ HCrO − 4 + H + is not well characterized. Reported values vary between about −0.8 and 1.6. [4] The dichromate ion is a somewhat weaker base than the chromate ion: [5]

The most common decay mode of a radioisotope of zinc with a mass number lower than 66 is electron capture. The decay product resulting from electron capture is an isotope of copper. [45] n 30 Zn + e − → n 29 Cu + ν e. The most common decay mode of a radioisotope of zinc with mass number higher than 66 is beta decay (β −), which produces ...
On the laboratory scale, LiAlH 4, zinc, and related reductants produce chromous chloride from chromium(III) precursors: 4 CrCl 3 + LiAlH 4 → 4 CrCl 2 + LiCl + AlCl 3 + 2 H 2 2 CrCl 3 + Zn → 2 CrCl 2 + ZnCl 2. CrCl 2 can also be prepared by treating a solution of chromium(II) acetate with hydrogen chloride: [6] Cr 2 (OAc) 4 + 4 HCl → 2 ...
