Detailed explanation-1: -Salinity is the measure of the amount of dissolved salts in water. It is usually expressed in parts per thousand (ppt) or percentage (%). Freshwater from rivers has a salinity value of 0.5ppt or less.

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: -Salinity is the measure of the number of grams of salts per kilogram of seawater, which is expressed in parts per thousand. Parts per thousand can be defined as how many parts, or grams, of salt there are per thousand parts, or kilogram (1, 000 g), of seawater. The symbol for parts per thousand is ‰.

Detailed explanation-4: -A salinometer is a machine that is capable of measuring the table salt (NaCl) content, known assalinity, of a solution. Another name for a salinometer is a conductivity meter, as dissolved salt in water will increase its ability to conduct electricity at measurable levels.

Detailed explanation-5: -What is salinity? Salinity is the dissolved salt content of a body of water. It is a strong contributor to conductivity and helps determine many aspects of the chemistry of natural waters and the biological processes within them.
