FAQ

Frequently Asked Questions

No, they are completely different. Disulfate refers to compounds with two sulfate (SO4) groups, while disulfide refers to compounds with a sulfur-sulfur (S-S) bond.

No, it is a highly technical term specific to chemistry and has no application in everyday conversation.

The standard British spelling is also 'disulfate', though the historical spelling 'disulphate' (following the 'sulphur'/'sulfur' distinction) is sometimes seen but is now less common.

Potassium disulfate (K2S2O7), also known as potassium pyrosulfate, is a classic example used as a flux in analytical chemistry.
