Specific conductivity is a measure of the ability of water to conduct an electrical current. It is highly dependent on the amount of dissolved solids (such as salt) in the water. Pure water, such as distilled water, will have a very low specific conductance, and sea water will have a high specific conductance.
Pure water has extremely low conductivity but any dissolved salts in the water increase its conductivity. Sea water with 3% salt has a high conductivity of 5 S/m.
Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.
yes it does
We need to measure the electrical conductivity.
by measuring the conductivity
The electrical conductivity of water is a measure of its ability to conduct electricity. Pure water is a poor conductor of electricity, but it can become more conductive when impurities or ions are present.
Water will conduct electricity if salt NaCl is dissolved in it. The conductivity is proportional to the salt concentration, and 3% gives a conductivity of 5 S/m, as in sea water.
One can accurately measure water resistivity by using a device called a conductivity meter. This device measures the ability of water to conduct electricity, which is directly related to its resistivity. By measuring the electrical conductivity of water, one can determine its resistivity accurately.
One reason is to teste the buoyancy of the water and density. Another reason is to test how the sea life is doing. Some marine animals can't live in salt water and some can't live in fresh water. They test the salinity to test if the water is suitable for life
Scientists measure salinity in water by using a device called a refractometer or by collecting water samples and conducting a chemical analysis in a lab to determine the amount of dissolved salts. Another common method is to use conductivity meters to measure the electrical conductivity of the water, which is directly related to its salinity.
Sea water has the best electrical conductivity. Ions from the salt can conduct electricity - but not very well.
