海水味鹹人所共知,但以少許含在口中試之,除鹹而外,還有微許苦澀不快之味。同時非僅苦澀,另外尚有一種類似(羊星)羶的異味,這足以證明海水裹面不僅含有食鹽,還包含着其他各種鹽分。溶解在海水中的鹽分究竟有多少?在遠離陸地,不受河水影響的地方,一公斤海水中平均含有三十五克,用百分此水表示即为3.5％。凡是溶於海水的鹽類,比重都比水高,因而海水較淡水的比重也大。假定淡水的此重作为一,那麼海水的比重就成为1.02～ Salty sea salty people are known, but with a little test in the mouth, in addition to salty, but also a little bitter bitter unpleasant taste. At the same time not only bitter, there is also a similar (sheep star) 膻 smell, which is sufficient to prove that the seawater wrapped not only contains salt, but also contains a variety of other salt. What is the amount of salt dissolved in seawater? On average, 35 kilograms of seawater per kilogram of seawater is far away from the land and 3.5% of the total salinity. Any salt soluble in seawater is heavier than water, so the proportion of seawater to freshwater is also large. Assuming this weight of freshwater as one, then the proportion of seawater becomes 1.02 ~
