Identify the species that is oxidized in step 2 and give a reason.
In step 3, 3.00 × 10−4 mol of thiosulfate ions, S2O32−, reacted completely with the iodine formed in step 2. Determine the amount of O2, in mol, in the water sample.
Calculate the concentration of oxygen in the water sample, in g dm−3. If you could not answer (b), use 2.00 × 10−4 mol instead; this is not the correct value.
Beeswax contains esters that form when long-chain carboxylic acids react with long-chain alcohols. State the name of this type of reaction.
[Ni(H2O)6]2+ is green, whereas [Ni(NH3)6]2+ is blue. Which statement best accounts for the different colours of the two complex ions? A. The two sets of ligands give different energy gaps between the split 3d orbitals, so light of different…
