The net ionic equation of the above reaction is
A.Fe3+ (aq) + Cloz (aq) + K+(aq) + OH - Fe(OH)3(s) + K+ (aq) + ClO3- (aq)
Fe3+ (aq) + OH -
B.Fe(OH)3(s)
C Fe(ClO3)2(aq) + KOH(aq) – Fe(OH)3(s) + KClO3(aq)
D.K+(aq) + ClO3 (aq) - KClO3(aq)

Answer 1

The net ionic equation for the reaction between Fe(ClO3)3(aq) and KOH(aq) resulting in Fe(OH)3(s) and KClO3(aq) is Fe3+(aq) + 3OH−(aq) → Fe(OH)3(s), after removing K+ and ClO3− ions which are the spectator ions.

Step-by-step explanation:

The student has asked about the net ionic equation for the reaction between Fe(ClO3)3(aq) and KOH(aq) that results in the formation of Fe(OH)3(s) and KClO3(aq). To write the net ionic equation, first, we balance the full equation:

Fe(ClO3)3(aq) + 3KOH(aq) → Fe(OH)3(s) + 3KClO3(aq)

Next, we write the complete ionic equation by separating the strong electrolytes into their ions:

Fe3+(aq) + 3ClO3−(aq) + 3K+(aq) + 3OH−(aq) → Fe(OH)3(s) + 3K+(aq) + 3ClO3−(aq)

Then, we remove the spectator ions (K+ and ClO3−) to find the net ionic equation, which only includes the species that participate in the reaction:

Fe3+(aq) + 3OH−(aq) → Fe(OH)3(s)
