![]() Gold is present in seawater-but only a tiny amount. Another notable difference is that blood has a negligible amount of the sulfate ion (SO 4 2−), but this ion is present in seawater. Although there is a negligible amount of the two hydrogen phosphate ions (HPO 4 2− and H 2PO 4 −) in seawater, there is a small amount in blood, where these ions affect acid-base properties. This difference is significant because the HCO 3 − ion and some related species have an important role in controlling the acid-base properties of blood. There is far more hydrogen carbonate ion (HCO 3 −) in blood than in seawater indeed, it is the third most common ion in blood. Most ions are more abundant in seawater than they are in blood, with some notable exceptions. ![]() Table 10.1 Percentage by Mass of Ions in Seawater and Blood Ion Table 10.1 "Percentage by Mass of Ions in Seawater and Blood" also lists the percentage by mass of ions in a typical sample of blood. ![]() Table 10.1 "Percentage by Mass of Ions in Seawater and Blood" lists the percentage by mass of the various ions in seawater.īecause it is highly likely that life on Earth originated in the oceans, it should not be surprising that many bodily fluids resemble seawater-especially blood. But about 3.5% of seawater is dissolved solids, mostly NaCl but other ions as well. It is likely that without seawater, no life would exist on Earth.Īt its simplest, seawater is mostly H 2O. More than 70% of the earth’s surface is covered by a very important solution-seawater. ![]()
