盐类的水解与酸碱中和滴定基础复习（Review of hydrolysis of salts and acid-base neutralization titration） Salt hydrolysis and neutralization titration based review.Txt life, face the fate of destruction. I do not love eolian dust, it seems to be mistaken by the front edge!! I only shed tears for the one I love most. I will learn to give up on you, because I love you too much. I won. I could give up the whole world and join the collection Sitemap Home The subject teaching curriculum teaching plan teaching reference thesis team preliminaries final results Aosai Gallery forum message resources course guiding classroom coaching example of extracurricular experiment to explore the basis of innovation of college entrance examination questions Zhenti special doubts solving prediction of junior middle school Your present position: Chemistry counseling Station, college entrance examination, basic review Salt hydrolysis and acid-base neutralization titration basis review: hxfdz article source: this site original hits: 54, update time: 2009-11-20 (1) hydrolysis of salts; Experiment: a small amount of sodium acetate, ammonium chloride and sodium chloride were put into three tubes containing distilled water, dissolved, and then examined with pH test paper. Phenomenon: CH3COONa pH7 NH4Cl pH7 NaCl pH=7 Thinking: sodium acetate and ammonium chloride are salt, strong electrolyte is dissolved in water, they fully ionized into ions and ionized ions in neither hydrogen ions nor hydroxyl ions Oh - and no doubt the proton ionization from the water; that is to say, the concentration of H + and out water ionization Oh the material is always equal, why not the same? Analysis： The ionized ions of sodium acetate play a role in water. CH3COO can produce acetic acid molecules with hydrogen ions in aqueous solution to ionization, so that the ionization of water moves in the direction of positive reaction, then decreased, increased, decreased, the solution is alkaline. Chemical equation for: CH3COONa + H2OCH3COOH +
