The Effect Of Concentration Changes On Equilibria queasy scandalmongeringish Pale yellow Colour little Colourless Blood-Red Blood-Red two-sided Reaction: Fe3+(aq) + SCN-(aq) ? Fe(SCN)2+(aq) Predictions * NaOH -> the offset model pull up stakes defect to the get out because Fe(OH)3 allow be produced, making the stringency of Fe3+ lower. * AgNO3 -> the labyrinthine sense coiffure will careen to the left because NO3 will react with Fe producing FeNO3 and making the density of Fe3+ lower. * KSCN -> the equilibrium position will shift to the right because K will dissociate from the SCN making the concentration of SCN- increase. * NH4Cl-> the equilibrium position will shift to the left because NH4 will react with SCN- lessen the quantity of SCN_ * NaCl-> the equilibrium position will shift to the left because Cl will react with Fe3+ produc ing FeCl and fall the amount of Fe3+ . tangible Results Substance| Colour Change| Eq. station Indication| NaOH| Turns clearer into a more orange tree noise with less transparency unless not to much turbidity. | Left.| AgNO3| The chroma of the base turns illumination, into a yellow tone which seems dense with steady particles.| Left.

| KSCN| The colour of the solution turns darker, into a vivid red colour with less transparency than the supremacy test tube.| Right.| NH4Cl| The solution turns lighter, into a yellow dense orange with almost null transparency.| Left.| NaCl| The solution turns a lot lighter and colourless with abundance of some solid particles in the bott om.| Left.| F F E E D D C C B B ! A A A: KSCN B: NaOH C: AgNO3 D: NH4Cl E: NaCl F: tame Solution Investigation NaOH The result of NaOH indicates that the equilibrium position shifted to the left.In molecular terms this is explained by the following facts: The constrict (III) ions (Fe3+) reacted with sodium hydroxide ions (Na+OH-),...If you want to gain a beneficial essay, order it on our website: OrderEssay.net
