-
Role of water in dissolving urea and nitric acid
Water is a polar solvent, which means that it can dissolve both ionic and polar covalent compounds. Urea and nitric acid are both polar covalent compounds, so they dissolve easily in water. This is important because it allows the urea and nitric acid to react with each other to form urea nitrate crystals.
-
Role of water in the formation of urea nitrate crystals
When urea and nitric acid are dissolved in water, they react with each other to form urea nitrate. The urea nitrate then crystallizes out of the solution. The water helps to slow down the reaction between the urea and nitric acid, which allows the urea nitrate crystals to grow larger and more perfect.
