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.

Does water have more positive or negative charges?
That depends on what you consider a charge. Electrons/protons? Compute approx. number of molecules, multiply by 10 for positive or negative charges. Water dipols? Compute approx. number of molecules for positive or negative charges. Ions/Anions? (Technically, this is not part of water, but salt solutions within it) Don't know how many milligrams of salt there is in an average cup of water.
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.
Why salt don't dissolve in water?
To understand why some salts don't dissolve in water, it's important to understand why those salts which are soluble do dissolve in water. Many types of salt are soluble in water, not just table salt (NaCl). Salts that dissolve in water are polar compounds. This means that one of the ends of the atom has a positive charge and the other side has a negative charge. These charges are normally strong enough to form an ionic bond and hold the molecule together. These charges are also what hold the molecules together into a crystalline structure. When the salt is put into water, the positive and negative charges of the water molecule pull the salt molecule apart into it's ions. In the case of NaCl, this would be the Na+ ion and the Cl- ion. The reason some salts don't dissolve in water is that they are not polar compounds. Since they aren't polar, the polar water molecules can't pull them apart into ions.
The attraction of opposite electrical charges plays a role in?
The attraction of opposite electrical charges play a role in ionic bonds.
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
A flow of electrical charges is known as an?
A flow of electrical charges running through a medium is known as an 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.
What is the different kind of ions?
Those with positive electrical charges, and those with negative electrical charges.
What are the three types of electrical charges?
positivenegativeneutralCommentWithout wishing to be picky, 'neutral' is not a type of charge -it is a lack of charge.
Electric current is defined as what?
Electric current is defined as the movement of electrical charges.
The energy of moving electrical charges?
Electrical energy
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.
