The average ocean salinity is 35 ppt: this means that in every kilogram of seawater (1000 grams), 35 grams are dissolved salt. Waters are considered fresh if they have less than 2 ppt. Because the water in estuaries is a mixture of fresh water and ocean water, the salinity in most estuaries is less than the open ocean. Sodium chloride or common salt is thechemical compound NaCl. It occursnaturally in many parts of the world as themineral halite and as mixed evaporites in saltlakes. Seawater contains an average of2.6% (by weight) NaCl, or 26 million metrictons cubic kilometer (120 million short tonsper cubic mile, an inexhaustible supply. A characteristic of seawater is that it is salty. It is usual to measure salinity in parts per thousand and the open ocean has about 35 grams (1.2 oz) solids per litre, a salinity of 35ppt. The Mediterranean Sea is a little higher at 37ppt and the Dead Sea has as much as 300 grams (11 oz) dissolved solids per litre (300ppt).

If salinity can be determined to 0.001 parts per thousand (g/kg) or 1 mg/kg (ppm) a major element is any ion with a However, it is to be noted that grams per milliliter (g/mL) and gram per cubic centimeter (g/cm 3) are not SI units. While discussing this topic in detail, water density is found to vary with respect to the level of salinity (or other impurities) and fluctuation of temperature. Of course, pressure does play a role in the subject of water denseness.

Salinity is the most important parameter characterizing and defining saline water, brine, or bittern. It is a measure of the total amount of salts dissolved in the water/brine, and brine, by definition, contains a lot of salt. It has been measured using many different units and in a number of ways.--chlorinity (C): corresponding with mostly 19 gram dissolved chloride per kilogram seawater. --salinity (S): corresponding with the total weight in grams of dissolved minerals per kilogram seawater. The equation establishing the link between the two stan- dards is: salinity = 1.805 chlorinity + 0.032.

Seawater is usually somewhere between 30 and 35 ppt, which means that a 1 liter bottle of seawater would have 30–35 grams of salt inside! In this experiment you will learn a simple way to measure the amount of salt in a sample of water by using evaporation. After the water of a solution evaporates, the dissolved salts are left behind. Dissolve those salts in water side by side, and the differences between them become nearly indistinguishable, just as they are when you use them to season your food. What does this mean for cooking? It means that if you are measuring by volume, different types of salt are not interchangeable.
