Keith, Metol is the only Sulphate in ID-11 they list it as bis(4-HYDROXY-N-METHYLANILINIUM) SULPHATE

This is one of the alternative ways of naming the chemical structure. Synonyms: Metol , p-(Methylamino)phenol sulphate , 4-Methylaminophenolsulphate , 4-(Methylamino)phenol hemisulphate salt , 4-Methylaminophenol sulphate.

Typical Tropical developer use Sodium Sulphate at levels like 40 to 199 grams per Litre.
