Compare ammonium fumarate and succinimide regarding their solubility in methanol and water. Which one is more soluble in water, and which one is more soluble in methanol?
Accepted Answer
Ammonium fumarate is a salt formed from a weak acid (fumaric acid) and a weak base (ammonia). Succinimide is a cyclic imide. Here's a comparison of their solubility:
Water: Ammonium fumarate is more soluble in water. It dissolves due to the formation of hydrogen bonds between the polar ammonium ions and water molecules. Succinimide, with its less polar structure, has lower solubility in water.
Methanol: Both ammonium fumarate and succinimide are likely to be more soluble in methanol than in water. Methanol is a polar protic solvent, and its ability to form hydrogen bonds with both compounds can enhance their solubility. However, ammonium fumarate is likely to be slightly more soluble in methanol due to the presence of ionic interactions.
Key Factors:
Polarity: Polar molecules are more soluble in polar solvents like water and methanol.
Hydrogen bonding: Compounds capable of forming hydrogen bonds with the solvent tend to be more soluble.
Ionic interactions: The presence of ions in ammonium fumarate contributes to its solubility in polar solvents.
