Justify that the following reactions are redox reactions:
Fluorine reacts with ice and results in the change: H2O(s) + F2(g) → HF(g) + HOF(g) Justify that this reaction is a redox reaction.
Consider the reactions: (a) 6 CO2(g) + 6H2O(l) → C6 H12 O6(aq) + 6O2(g) (b) O3(g) + H2O2(l) → H2O(l) + 2O2(g) Why it is more appropriate to write these reactions as : (a) 6CO2(g) + 12H2O(l) → C6 H12 O6(aq) + 6H2O(l) + 6O2(g) (b) O3(g) + H2O2 (l) → H2O(l) + O2(g) + O2(g) Also suggest a technique to investigate the path of the above (a) and (b) redox reactions.
How do you count for the following observations ?
Consider the reactions : 2 S2O32– (aq) + I2(s) → S4 O62–(aq) + 2I–(aq) S2O32–(aq) + 2Br2(l) + 5 H2O(l) → 2SO42–(aq) + 4Br–(aq) + 10H+(aq) Why does the same reductant, thiosulphate react differently with iodine and bromine ?
Why does the following reaction occur ? XeO64– (aq) + 2F–(aq) + 6H+(aq) → XeO3(g)+ F2(g) + 3H2O(l) What conclusion about the compound Na4XeO6 (of which XeO64– is a part) can be drawn from the reaction.
