As a result, acetanilide is more likely to dissolve in hot water than in cold water. Nam risus ante, dapibus a molestie consequat, ultrices ac magna. 30 grams of NaNO_3 is dissolved in 892 grams of water. Search for free and find new suppliers for chemical products, pharmaceuticals and APIs. The solubility of NaCl at 17 degrees celsius is 39 g per 100 ml water. Acetanilide is moderately soluble in boiling water, but its much less soluble in room temperature and cold water. The increased kinetic energy of the solvent molecules at higher temperatures allows them to more effectively interact with and dissolve the solute, resulting in higher solubility. mol 1: 3D model : Interactive image; Density: 1.263 g/cm 3: Melting point: 169 C (336 F) Solubility in water: .
