ASAP Why do instruments that measure conductivity determine the salinity of ocean water?
because dissolved solids in water conduct electricity
because oceans generate electricity
because pure water conducts electricity
because salt conducts electricity

A

Explanation:

Electrical Conductivity of water is its ability to conduct an electric current. Salts or other chemicals that dissolve in water can break down into positively and negatively charged ions. These free ions in the water conduct electricity, so the water electrical conductivity depends on the concentration of ions.
