易错句子Hot water dissolvents sugar faster than cold water.
正确表达Hot water dissolves sugar faster than cold water.
dissolvent 是名词,指能溶解其他物质的“溶剂、溶解剂”;表示“溶解”这个动作要用动词 dissolve,第三人称单数为 dissolves。不能因为词尾是 -ent 就把它当动词用,句中作谓语的是动作,所以应改为 dissolves。

易错句子Stir the powder until it turns into a clear dissolvent.
正确表达Stir the powder until it turns into a clear solution.
dissolvent 指起溶解作用的物质,即溶剂;粉末溶解后得到的液体是 solution(溶液)。汉语“溶解剂”和“溶液”都含“溶”字,容易混用,但英语里前者是施动者、后者是溶解的结果,因此句中“变成清澈的液体”应说 solution。

易错句子Many dissolvent can dissolve grease.
正确表达Many dissolvents can dissolve grease.
dissolvent 是可数名词,复数为 dissolvents;many 后面必须接可数名词复数。汉语名词没有数词形变化,容易漏掉复数词尾 -s,这里需用 dissolvents 与 many 保持一致。
dissolvent 是较书面、较少用的词,可指起溶解作用的物质,也可指被溶解的物质;solvent 是化学和日常语境里最常用的“溶剂”,专指溶解别人的那方液体,另有形容词义“有偿付能力的”,此时绝不能换用 dissolvent。
solute 只指被溶解的那一方(如盐水中的盐),不能指起溶解作用的液体;dissolvent 语义较宽,两者方向都可能涵盖,所以强调“被溶解的成分”时应选 solute。
solution 指溶解之后形成的均匀混合物,即溶解的结果,而不是起溶解作用的物质;它还有“解决方案”的常用义,这是 dissolvent 完全没有的。
