一、酸溶液和酸性溶液酸溶液是酸溶解在水中得到的水溶液 ,该溶液一般均呈酸性 ,溶液中电离出的阳离子只有H+,而酸性溶液是溶质溶解在水中 (或其它溶剂中 )所得的溶液 ,溶液呈酸性其溶质不一定是酸。如硫酸氢钠 ,由于硫酸氢钠溶于水后发生如下电离过程 :NaHSO4 Na++H++SO4 2 - ,也产生了H+但 1. Acid solution and acid solution The acid solution is an aqueous solution of acid dissolved in water. The solution is generally acidic. The cations ionized in the solution are only H+, while the acidic solution is the solute dissolved in water (or other solvent). In solution, the solution is acidic and its solute is not necessarily an acid. Such as sodium bisulfate, due to the dissolving of sodium bisulfate in water, the following ionization process occurs: NaHSO4 Na++H++SO4 2 - , but also produces H+ but
