Question

A student staying in a coastal region tests the drinking water and also the sea water 'With a circuit in which a part of the connecting wire is wound around a matchbox containing compass. He finds that the compass needle deflects more in the case of sea water. Can you explain the reason?

Answer 1

Answer:

because it is salty water and unfit for use it is used for only the electricity blowing and making salt and the other manufacturers think that's why the compass needle defect more cores in of the sea water

Answer 2

Conductivity of sea water:

• Drinking water has less salinity compared to sea water.
• Salt is nothing but NaCl, when electric current is passed through salt water sodium chloride undergoes ionises and forms into sodium and chloride ions.
• The sodium is positive ion and chloride is negative ion.
• These ions conduct electricity. If the salinity of the water increases, the conductivity of the water also increases.
• The magnetic field produced by electricity depends on the electric current flowing through solution.
• If the electricity is more then the magnetic field produced is also more.
