Lead Nitrate vs. Zinc Nitrate
Zinc nitrate is also highly soluble in water and ethanol, and it decomposes at a higher temperature compared to lead nitrate, around 262°C. While both compounds are soluble in water, lead nitrate has a higher density than zinc nitrate. This difference in density can be attributed to the atomic mass of the metal ions present in each compound.
