Descripción
Sumario:1. The nature of the reaction between gelatin and sodium hydroxide has been studied at three concentrations of gelatin. 2. Gelatin appears to react stoichiometrically with sodium hydroxide. 3. The addition of gelatin to sodium hydroxide does not change the concentration of sodium ions in the solution. 4. A given amount of gelatin reacts with the same amount of sodium hydroxide no matter what the concentration of sodium hydroxide or ratio of sodium hydroxide to gelatin, provided there is sufficient excess of sodium hydroxide to prevent hydrolysis. 5. The combining weight of dry gelatin as an acid is found to be 1370 gm.
