The reaction between HI and FeCl3 is balanced, as shown below:

  • The general equation is FeCl3 + HI —>HCl + FeCl2+ I2
  • The number of moles in the reactants and products side is shown in the table below.
ElementsReactantsProducts
Table representing the number of moles of reactants and products
  • The number of moles of I is to be multiplied by 2 on the reactant side to balance it.
  • Also, the number of moles of H has to be multiplied by 2 on the product side.
  • The number of moles of Cl is unbalanced, so to balance it, multiply it by 3 on the product side and by 2 on the reactant side.
  • Hence, the number of moles of Fe is also balanced.
  • The balanced equation is,2 FeCl3 + 2HI —>2HCl + 2FeCl2 + I2.

HI + FeCl3 net ionic equation.

  • The ionic equation is 2Fe3+(aq) +2I- (aq) —> 2Fe2+ (aq) + 2I(g).
  • The state of elements in the ionic equation of the HI + fecl3 reaction is as follows
  • 2 HI (aq) +2 FeCl3 (aq) —>2 FeCl2 (aq) + 2HCl (aq) +I2(g).
  • The ionic equation of each element is as follows:2H+(aq)+ 2I-(aq)+2Fe3+(aq)+6Cl-(aq) —> 2Fe2+(aq) + 4Cl- (aq) + 2H+ (aq) + 2Cl- (aq)+ 2I(g).
  • The same ions from either side gets canceled. Therefore,2Fe3+(aq) +2I- (aq) —> 2Fe2+ (aq) + 2I(g).

Is HI + FeCl3 a conjugate pair?

HI + FeCl3 do not have conjugate pair because they do not have a difference in their proton number to form a conjugate pair.
