Is ammonium binoxalate dangerous?

Yes, it is an irritant to skin, eyes, and respiratory system, and is toxic if ingested. It must be handled with appropriate personal protective equipment (PPE).

What is the difference between ammonium binoxalate and oxalic acid?

Ammonium binoxalate is a salt where one hydrogen ion of oxalic acid is replaced by an ammonium ion (NH₄⁺). It is less acidic than pure oxalic acid but shares similar chemical properties.

Where might I encounter this chemical?

In a chemistry laboratory, in certain specialised metal or stone cleaning products, in photography development processes, or in historical textile manufacturing contexts.

Why is it sometimes called 'salts of sorrel'?

This is an old, non-systematic name. Oxalic acid is found in plants like sorrel, and 'salts' refers to its salt form with ammonium. The modern IUPAC name is preferred for clarity.

Is “ammonium binoxalate” formal?

Ammonium binoxalate is usually highly technical/scientific in register.
