A strong base such as sodium hydroxide is not necessary in this particular case. v Recovery of a portion of these inorganic compounds is possible lby rst dissolving the product in water, and then carbonating the resulting aqueous solution to convert the sodium carbonate portion to sodium bicarbonate and to precipitate therefrom sodium bicarbonate. The key is to react the benzoic acid with sodium bicarbonate and separate the benzoate out first. The amount of sodium bicarbonate (0. sodium hydroxide to extract 2-naphtholate. Thus, by adding sodium bicarbonate and ether to the benzoic acid-naphthalene mixture, one is left with immiscible aqueous sodium benzoate and naphthalene-in-ether solutions. 10 (p. 00002 mol, so that can be considered negligible. Lastly, the organic layer is extracted with 5 mL of saturated aqueous sodium chloride to remove any excess water to obtain pure isopentyl acetate. 382. Sodium bicarbonate is a multifaceted medication that plays a crucial role in managing and treating diverse disease pathologies. 0 M sodium bicarbonate (NaHCO3). = 1 mL x (1 L/ 1000 mL) x (1 mol/ 1 L) = 0. Failing to mix the sodium bicarbonate with the organic layer fully would cause the product to not fully be extracted. 734) to separate the following two-component mixtures. We have chosen to extract the acidic compound into the aqueous layer using sodium hydroxide. The remainder is converted into sodium bicarbonate in a carbon-ating tower by reaction with carbon dioxide and water.
