Enter an equation for the precipitation reaction that occurs (if any) when solutions of potassium hydroxide and nickel(ii) bromide are mixed. express you answer as a chemical equation including phases.

Precipitation reaction is defined as the reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.

The chemical equation for the reaction of potassium hydroxide and nickel (II) bromide follows:

[tex]2KOH(aq.)+NiBr_2(aq.)\rightarrow Ni(OH)_2(s)+2KBr(aq.)[/tex]

By Stoichiometry of the reaction:

2 moles of aqueous solution of potassium bromide reacts with 1 mole of nickel (II) bromide to produce 1 mole of solid nickel (II) hydroxide and 2 moles of potassium bromide

Hence, the chemical equation is written above.

The reaction of potassium hydroxide and nickel(ii) bromide is; NiBr2(aq) + 2KOH(aq) -------> Ni(OH)2(s) + 2KBr(aq)

A precipitation reaction is a reaction in which one of the products obtained when two aqueous solutions are mixed is a solid. This solid obtained by mixing two aqueous solutions is called a precipitate.

Let us now look at the reaction between solutions of potassium hydroxide and nickel(ii) bromide, the reaction occurs as follows;

NiBr2(aq) + 2KOH(aq) -------> Ni(OH)2(s) + 2KBr(aq)
