This substance is insoluble in ethanol.
1. Different molecular structures: The molecular structure of bismuth resin has longer alkyl side chains, and the ethanol molecules are smaller, making it difficult to interact with the molecules of bima resin.
2. Difference in polarity: Bima resin is non-polar, while ethanol is polar, resulting in a weak interaction between the two.
3. Different solubility parameters: The solubility parameters of bima resin and ethanol are quite different, making it difficult to dissolve each other.
