Question

The following chemical reaction takes place in aqueous solution: FeBry(aq)+2 KOH(aq) Fe(OH)2(s)+2 KBr(aq) Write the net ionic equation for this reaction.

Answer 1

Answer: Fe^2+ (aq) + 2OH^- (aq) --> Fe(OH)2 (s)

Step-by-step explanation:

The chemical reaction follows the equation:

FeBr2 (aq) + 2 KOH (aq) --> Fe(OH)2 (s) + 2KBr (aq)

The aqueous ionic substances separate into their respective ions (note that the solid precipitate Fe(OH)2 (s) does NOT separate):

Fe^2+ (aq) + 2Br^- (aq) + 2K^+ (aq) + 2OH^- (aq) --> Fe(OH)2 (s) + 2K^+ (aq) + 2Br^- (aq)

Then, cancelling out the ions that appear on both sides gives us the net ionic equation for the reaction:

Fe^2+ (aq) + 2OH^- (aq) --> Fe(OH)2 (s)
