That means you will precipitate: We can calculate the solubility of a gas at a new pressure using Henry's law. Solubility in water <0.56 g/100 mL (25 C) Solubility: Soluble in ethanol, diethyl ether, acetone, benzene: log P: 1.16 (23 C) Vapor pressure: 2 Pa (20 C) Does Acetanilide dissolve in cold water? Solubility of acetanilide in water at 25 C: < 0.56 % ( w / v) ( Wikipedia) Here, as a novice to organic chemistry, you may concern mainly on number of carbons in each molecule (aside other factors such as presence of N and O) to decide the solubility. However, acetanilide is only slightly soluble in water. Acetanilide has a much higher solubility in hot water than in cold water. A and then homogeneity at 80C corresponds to the answer.

In the 19th century acetanilide was one of a large number of compounds used as experimental photographic developers. Since acetanilide (AT) is more soluble than acenapthene at this temperature (see Figure 3.28), it should also completely dissolve in 12.5mL of hot ethanol. background: #EFEFEF; The solubility of acetanilide in hot water 5. .
