Yes, silver nitrate (AgNO3) is soluble in water. When it is added to water, it dissociates into silver ions (Ag+) and nitrate ions (NO3–). This high solubility is due to the polar nature of both the silver cation and the nitrate anion, which interact well with water molecules.
Silver nitrate is often used in various applications, including photography, analytical chemistry, and as an antiseptic. Its ability to dissolve in water makes it useful in these fields, as it can easily be prepared in solution form for various reactions and processes.
