The balanced chemical reaction with potassium hydroxide and nickel(II) bromide as reactants is: 2KOH(aq) + NiBr2(aq) -> 2KBr(aq) + Ni(OH)2(s)

In this reaction, potassium hydroxide (KOH) is the strong base and nickel(II) bromide (NiBr2) has characteristics of a Lewis acid. One of the products is potassium bromide (KBr), an ionic salt. The other one is the precipitate, nickel(II) hydroxide Ni(OH)2, that appears as apple-green powder.
