Because the salt water is salt dissolved water, which is NaCl plus water. When the NaCl dissolve in the water, they breaks down into sodium ion (contains positive charge) and chloride ion (contains negative charge), so that the salt water has electrical charges. Actually we can't say it has charges, we only can say that it can conduct electricity.

Why salt is needed to conduct electricity?
Ultrapure water is a bad conductor; you need a salt, which form ions, to increase the electrical conductivity.
What is a salt water generator?
A salt water generator, also known as a salt chlorinator, is a device that converts salt into chlorine to sanitize and disinfect pool or spa water. It works by passing an electrical current through salt water, which then produces chlorine gas that dissolves into the water. This eliminates the need for traditional chlorine chemicals to be added to the water on a regular basis.
Does water have more positive or negative charges?
Water molecules are neutral, meaning they have the same number of positive and negative charges overall. Each water molecule consists of two hydrogen atoms (positive charges) and one oxygen atom (negative charge), balancing out the charges to create a neutral molecule.
What property makes salt an electrolyte?
Salt is an electrolyte because it dissociates into its constituent ions (sodium and chloride) in solution. These ions are then able to carry electrical charges by facilitating the flow of electricity.
Why salt don't dissolve in water?
Salt dissolves in water due to the attraction between the positive and negative ions of the salt and the polar water molecules. The dissolving process breaks the ionic bonds of the salt, allowing the ions to be surrounded and carried away by the water molecules. Salt is considered soluble in water because of these interactions.
Why is salt and pepper attracted to a straw after its been rubbed on felt or wool?
Both the salt and the pepper are attracted to the straw because of electrical charges. When you rub the straw on the wool/felt, those electrical charges are created.
When a soluble metallic salt is added to water its electrical conductivity decreases?
No. Its electrical conductivity increases because the positive and negative ions of the salt dissociate in the water.
Does concentration of salt in the water affect the amount of electrical charge?
no
Why is it possible to run an electrical current through salt water and not pure water?
Pure water does not contain any electrolytes to carry electrons where as salt water contains the same to carry electrons -movement of electrons is electrical current
Which water is better for electrical conduction boiled water sea water distilled water ordinary water?
Sea water has the best electrical conductivity. Ions from the salt can conduct electricity - but not very well.
Electrical charges flow in the same path?
Electrical charges will not flow. The considered to be held stationary.
A flow of electrical charges is known as an?
A flow of electrical charges running through a medium is known as an electrical current.
Why is salt added to earthing?
Since this is an electrical forum I assume you are talking about what we in the US call "grounding". Salt improves the conductivity of water by providing ions necessary for transmission of electrical current.
Electric current is defined as what?
Electric current is defined as the movement of electrical charges.
What type of energy is carried by moving negative charges?
That is the electric energy. It is called the electricity
What form of energy is moving electrical charges?
Moving electrical charges create electrical energy.
How do electrons help the salt be a better conductor of electricity?
Salt in water solution or melted salt are electrical conductors because they contain ions Na+ and Cl-.
