Bismuth itself is insoluble in water. This means that pure bismuth metal does not dissolve in water. However, certain bismuth compounds can be soluble in water depending on their chemical nature.

For example, bismuth salts such as bismuth nitrate (Bi(NO3)3) and bismuth chloride (BiCl3) are soluble in water. When these compounds dissolve in water, they dissociate into their constituent ions, which can then interact with water molecules.

But elemental bismuth (Bi) itself does not dissolve in water because it is a metal, and metals generally do not dissolve in water due to their metallic bonding nature.
