Cobalt(II) bromide Cobalt(II) bromide
The systematic name of CoBr2 is cobalt(II) bromide.
Are we talking of C(=O)Br2 or CoBr2 . Careful with the letter 'O/o'.
The spectator ion in the reaction between KOH and CoBr2 is K+ (potassium ion). When potassium hydroxide (KOH) reacts with cobalt(II) bromide (CoBr2), cobalt hydroxide Co(OH)2 is formed as a precipitate, while potassium ions remain unchanged in the solution.
CoBr2 is an ionic compound because it is composed of a metal (cobalt) and a nonmetal (bromine). Ionic compounds form due to the electrostatic attraction between positively charged metal cations and negatively charged nonmetal anions.

Co2+ is an ion. But it will combine with any anion to form a compound as in CoCl2 or CoBr2.

Most metal halides are water soluble, and cobalt (II) bromide is no exception.
CoBr2 is named cobalt(II) bromide. In this compound, cobalt has a +2 oxidation state, which is indicated by the Roman numeral II in the name. The "bromide" part refers to the bromine ions, which have a -1 charge. Therefore, the overall formula reflects one cobalt ion and two bromide ions to balance the charges.
No, silver (Ag) will not react with cobalt(II) bromide (CoBr2) under normal conditions because silver is less reactive than cobalt. Silver is a noble metal and is typically unreactive towards most other elements.
In water solution potassium ion (K+) is a spectator ion, it does not react because both KOH and KBr are soluble salts (the first strongly basic, the last a neutral salt)
CoBr2 is composed of cobalt ions (Co²⁺) and bromide ions (Br⁻). In this compound, each cobalt ion has a +2 charge, while each bromide ion has a -1 charge. As there are two bromide ions for each cobalt ion, the overall charge balance is maintained, resulting in a neutral compound. Thus, the formula reflects one cobalt ion and two bromide ions.
