TaigaOceanographers measure the conductivity of seawater to calculate its salinity, as salinity affects water density and thus ocean circulation patterns. Conductivity is used because the salt in seawater makes it a good conductor of electricity, and this property can be easily measured to determine salinity levels.
Pure water does not conduct electricity, because there are no free electrons. In salt water, the sodium chloride dissolves to form negatively charged chlorine atoms and positively charged sodium atoms, which WILL conduct electricity. So measuring the conductivity of the water will give you an indication of the amount of salt dissolved.
One reason for measuring conductivity in seawater is to determine the salt content. Absolutely pure water is actually a pretty good insulator with low conductivity. As materials dissolve into it, the conductivity shoots up (water is an excellent solvent it seems). By measuring electrical and thermal conductivity of sea water you can quickly get a good handle on how much salt and other material is dissolved into it.

What laboratory equipment can be used to take metric measurements?
Laboratory equipment such as graduated cylinders, beakers, and pipettes can be used to take metric measurements. These tools are calibrated in metric units such as milliliters and centimeters.
What is the name of the instrument that is used to drop out of an aircraft to take measurements inside hurricanes?
These instruments are called dropsondes.
How you can measure the electric conductivity of solid liquid mixture?
One way to measure the electrical conductivity of a solid-liquid mixture is by using a conductivity meter. By placing the electrodes of the meter into the mixture, it can detect the flow of electric current and provide a reading of the conductivity level. Another method is to calculate the conductivity by measuring the resistance of the mixture using a multimeter and then using this value in the formula to determine conductivity.
Why electrolysis does not take place in distilled water?
Electrolysis requires ions in water to conduct electricity. Distilled water lacks ions, so it has very low conductivity and does not support electrolysis. Adding a small amount of electrolyte (such as salt) to distilled water increases its conductivity, enabling electrolysis to occur.
Does Uranus have man made moons?
No, Uranus does not have a man made moon. We have sent probes by there to take scientific measurements and photographs, but no satellites or other man-made objects are there.
