Chloride and Salinity
The salinity level in seawater is fairly constant at about 35 ppt (35000 mg/L) while brackish estuaries may have salinity levels between 1 and 10 ppt Since most anions in seawater or brackish water are chloride ions salinity can be determined from chloride concentration The following formula is used: salinity (ppt) = 0 0018066 5 Cl– (mg/L) |

How to calculate salinity based on chloride concentration?
Use this formula to calculate the salinity, based on the chloride concentration, Cl– salinity (ppt) = 0.0018066 5 Cl– (mg/L) Record this value in the Data & Calculations table (round to the nearest 0.1 mg/L Cl–). Record the chloride concentration value (in mg/L Cl –) from the computer. salinity (ppt) = 0.0018066 5 Cl– (mg/L).
How do you measure chloride concentration?
Record the chloride concentration value (in mg/L Cl –) from the computer. salinity (ppt) = 0.0018066 5 Cl– (mg/L). This test can be conducted on site or in the lab. A 100-mL water sample is required.
What is a normal chloride concentration for groundwater?
A chloride range of 35-125 mg/L for groundwater is considered normal. 3. When the chloride concentration is greater than 250-400 mg/L, the water will taste salty. 4. Seawater has a chloride concentration of about 19,400 mg/L. 5. Seawater has a salinity of 35,00 mg/L. 6. Brackish water has a chloride concentration between 500-5,000 mg/L. 7.
How much chloride ion is in seawater?
Seawater has a chloride ion concentration of about 19,400 mg/L (a salinity of 35.0 ppt). Brackish water in tidal estuaries may have chloride levels between 500 and 5,000 mg/L (salinity of 1 to 10 ppt). Even freshwater streams and lakes have a significant chloride level that can range from 1 to 250 mg/L (salinity of 0.001 to 0.5 ppt).
Prof. Boyd Offers A Guide For Preparing Artificial Seawater
At Aquaculture America 2020 in Honolulu, several papers were presented on artificial seawater concoctions, indicating a general interest in this topic. This short article provides information on the typical chemical characteristics of seawater, which may serve as a guide for those preparing artificial seawater. Formulas for making artificial seawat
Characteristics
The salinity of seawater varies somewhat from as low as 31 ppt in some areas of the ocean to as much as 41 ppt in the Red Sea. The average value most commonly reported is 35 ppt, but some authors use 34.5 ppt. The density (specific gravity) of seawater ranges from 1.020 to 1.030 kg per liter (or grams per cubic centimeter). The average usually is r
Major Ions
The major ion concentrations in seawater may vary slightly from place to place even when there are no differences in salinity. However, when salinity increases, the major ion concentrations all tend to increase more or less in direct proportion to the salinity. Many authors have reported the major ion composition of seawater. Major ions are those w

When one makes or has an independent laboratory make an analysis of the seawater, the cation-anion balance principle may be used to check the probable reliability of the analysis. This is illustrated below for the Goldberg seawater analysis (Table 1): globalseafood.org
Trace Elements
In the event someone is interested in the trace element composition of seawater, three reports of several common trace elements are provided (Table 2). Note that the variation is much greater than for the major ions. But, of course, it is much more difficult to make accurate analysis of trace elements than of major ions. Seawater contains many more

One other point of possible interest to readers is that seawater is usually at or very near calcium carbonate saturation. Thus, liming materials applied to marine aquaculture waters often do not dissolve. globalseafood.org
