'MgSO4·7H2O' and 'MgSO4 x 7 H2O' are the same substance written two ways — `·` where the twin uses ` x ` — so the pair escaped dedup, and the loser was then grounded to the nearest term lexical matching could reach: CHEBI:32599 ('magnesium sulfate'), which does not carry the water its own label states.
