Cation/ Anion List Worksheet for naming ions Students enrolled in Dr. Draganjac's Introduction to Chemistry (CHEM1003), General Chemistry I (CHEM1013) and General Chemistry II (CHEM1023) classes are responsible for learning the names and formulae for the common acids and common reagents and for learning the names, formulae and the charges for the common cations and anions listed below: Mercury(II) bromide HgBr2 6.2×10^-20. [5], In the solid state CuBr2 has a polymeric structure, with CuBr4 planar units connected on opposite sides to form chains. sample calc of solubility: Tl2S(s) ⇋ 2Tl^+(aq) + S^2-(aq) Ksp = [Tl^+]^2[S^-] = 6×10^-22. PubChem Substance ID 24853260. However, barlowite, Cu4BrF(OH)6, is worth of mention. [10] Experiments have also shown copper bromide treatment to be beneficial for skin rejuvenation. Purification: recryst from H2O and dried in vacuo.35. The charge of bromide is Br- because it is in group 17 only needing 1 electron to have a full outer shell so it wants to gain an electron so there will be 1 more electron then protons giving it -1 or - charge.
