Unfortunately, there is currently no Zn(NO3)3 in chemistry. You might be confusing Zn(NO3)2 – Zinc Nitrate and Al(NO3)3 – Aluminium Nitrate.
Zn(NO3)2 is a salt of the metal Zinc (Zn) with Nitric Acid (HNO3). This substance usually appears in the form of white, odorless crystals, which are highly soluble in water. Zn(NO3)2 is widely used in the industry to produce electronic materials, ceramics, circuit contacts and in the process of electrolysis.
Like many other nitrate salts, Zn(NO3)2 can react with metals, acids, non-metals and other salts. Specifically, when reacting with metals like Cu, Fe, this substance can form new salts and release hydrogen gas. When reacting with acids, Zn(NO3)2 can form salts and water. And when reacting with non-metals and salts, this substance can form other substances.
Zn(NO3)2 is usually prepared through a reaction between Zinc metal and Nitric Acid. However, caution must be exercised in the preparation process as this reaction produces harmful Nitric Oxide gas.
Al(NO3)3 – Aluminium Nitrate, is also a salt of the metal Aluminium (Al) with Nitric Acid (HNO3). This substance is in the form of white, odorless crystals which are easily soluble in water. Al(NO3)3 is commonly used in the industry to produce aluminium materials and as a cleaning agent.
