it is not the acid ether concentration technique which produces four layers, but the formalin-ether concentration technique, which, at the end of the procedure after centrifugation will produce an upper layer of ether, a second layer of fat debris, a third layer of formalin and the bottom layer of sediments which contain your eggs and cysts...
Because acid dissolves in water and alcohol dissolves in ether
In this step of the experiment you are trying to separate benzoic acid from biphenyl an impurity. Sodium hydroxide reacts with benzoic acid to form (ar-O-O(-)na(+)) and (H2O), this allows for the ether layer containing biphenyl to separate as the precipitant, which we can now extract and discard.
The layer that would settle at the bottom of a bottle would be the one with the biggest density. For example, if you would have a mixture of water and an ether, the ether would be on top because it has the smallest density.
The outermost layer of most fish is scales.
