    "Concentrated solution"(浓溶液)是化学中描述溶液浓度的术语,具体含义和特点如下:

    1. 定义
      浓溶液指在特定温度和压力下,溶质含量较高的溶液。其特点是单位体积溶剂中溶解的溶质较多,但并未达到溶解度的上限(即不一定是饱和溶液)。例如,一杯溶解了大量糖的水可称为浓糖水,只要糖未完全析出。

    2. 与相关概念的区别

      • 稀溶液:溶质含量较低,与浓溶液形成对比。
      • 饱和溶液:溶质达到最大溶解量,无法继续溶解。浓溶液可能未饱和(如高溶解度物质形成的溶液),而低溶解度物质的浓溶液可能接近饱和。
    3. 物理性质
      浓溶液通常表现出更强的依数性,如沸点升高(如浓盐水沸点高于纯水)、凝固点降低。若溶质为电解质(如浓硫酸),其导电性显著增强;非电解质浓溶液(如浓糖水)导电性则较弱。

    4. 应用与示例

      • 实验室:常用浓溶液稀释配制所需浓度(如浓盐酸稀释为稀盐酸)。
      • 工业:浓硫酸用于脱水剂,浓盐水用于食品腌制。
      • 日常:高浓度糖浆、医用酒精(浓度约75%)等。
    5. 浓度表示方法
      常用质量分数($text{质量分数} = frac{text{溶质质量}}{text{溶液总质量}} times 100%$)或摩尔浓度($c = frac{n}{V}$,单位mol/L)描述浓度。

    总结来说,浓溶液强调溶质比例高,但需结合具体场景判断其实际状态。实际应用中需注意安全,某些浓溶液(如强酸、强碱)可能具有腐蚀性。
