Detailed explanation-1: -Salinity is the amount of dissolved salts or ions in seawater. The unit of measurement is grams of salt per 1000 grams of seawater or simply parts per thousand (written as ‰).

Detailed explanation-2: -The term “salinity” refers to the concentrations of salts in water or soils. Salinity can take three forms, classified by their causes: primary salinity (also called natural salinity); secondary salinity (also called dryland salinity), and tertiary salinity (also called irrigation salinity).

Detailed explanation-3: -Ionic compounds such as sodium chloride, that dissolve in water and dissociate to form ions, are called electrolytes.

Detailed explanation-4: -Salinity-Salinity is the amount of salt in grams present in 1000 grams of water. The average salinity of the oceans is 35 parts per thousand.
