Is iminodisuccinic acid more soluble in water than fumaric acid?

Accepted Answer

Iminodisuccinic acid (IDA) is more soluble in water than fumaric acid. This is due to the presence of the amine group (-NH-) in IDA, which can form hydrogen bonds with water molecules. Fumaric acid, on the other hand, only has carboxyl groups (-COOH), which can also form hydrogen bonds, but to a lesser extent than the amine group. The increased hydrogen bonding capability of IDA makes it more soluble in water.
