Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 94-91-7, C17H18N2O2.

The reaction of trans-[Fe(Salpn 1,2)(OH2)2]+ (Salpn 1,2 = N,N’-propylene 1,2 -bis-salicylidiniminate) with SIV has been studied at 20.0 ? t/C ?35.0, 0.01 < [sIV]T/mol dm-3 < 0.10 (I= 0.3 mol dm-3) in aqueous acetate buffer medium of varying pH (= 3.80 - 5.20). The stopped flow and rapid scan spectrophotometric measurements indicate the formation of monosulphito complex, trans-[Fe(Salpn 1,2)(OH2)(SO3)]. The trans- diaqua complex reacts with HSO3- ?10 times slower than its (hydroxo aqua) analogue thus displaying the labilising effect of the coordinated hydroxo group. The limiting dissociative mechanism (D) appears to be applicable for the aqua ligand substitution of the aqua-hydroxo complex, trans[Fe(Salpn 1,2)(OH2)(OH)]. The trans-[Fe((Salpn 1,2)(OH2)(SO3)]- undergoes redox reaction yielding FeII, SO42- and S2O62-; kobs = k1 red + k2 red [HSO3-] + k3 red [H+][HSO3-] is obeyed with k1 red = (0.64 ± 0.40) x 10-4 s-1, k2 red = (1.8 ± 0.9) x 10-4 dm3 mol-1s-1 and k2 red = (1.4 ± 0.1) x 102 dm6 mol-2 s-1 30.0C (I= 0.3 mol dm-3). The electron transfer is innersphere type for the uncatalysed path (k1 red) while the exact mechanism for the HSO3- and (H+ + HSO3-) dependent paths remains equivocal. Interested yet?
