WebMar 9, 2024 · So this is basically “parts per part,” meaning that for one part solution you have 0.0002 parts salt. But of course, having this many decimal points isn’t exactly convenient, so to convert to PPM you multiply by 1,000,000 = 10 6, giving: 0.0002 × 10 6 = 220 PPM. The general approach works for volume calculations, too. WebJun 8, 2024 · Current seawater extraction techniques find it difficult to separate lithium from competing ions of sodium, magnesium and potassium. Moreover, the low lithium concentration of approximately 0.2 parts per million (ppm) makes separation expensive. However, almost all of the world’s lithium lies in the world’s oceans.

For example, the addition of 1 µmol kg−1 HCl to distilled water at pH 7 reduces the pH to very close to 6. The same addition to seawater at pH 7 and ΣCO2 = 2000 µmol kg−1 at T=15°C and S=35 only reduces the pH to 6.997. The seawater pH buffer is mainly a result of the capacity of CO32− and HCO3

Web5.3 Salinity Patterns. . Salinity of seawater is usually expressed as the grams of salt per kilogram (1000 g) of seawater. On average, about 35 g of salt is present in each 1 kg of seawater, so we say that the average salinity of the ocean salinity is 35 parts per thousand (ppt). Note that 35 ppt is equivalent to 3.5% (parts per hundred). Webof seawater, i.e. seawater can resist drastic pH changes even after the addition of weak bases and acids.
