How does dissolving salt in water allow electricity current to flow?

When salt dissolves in water its ions separate and they become free to move. The positive ions are attracted to the negative electrode (the cathode). The negative ions go to the anode. Positive and negative ions from the water also do this. Some of the ions are discharged. The net result is that a current flows in the external circuit, and the salt is chemically changed. If it is sodium chloride, hydrogen is produced at the cathode, chlorine at the anode and sodium hydroxide in the solution.

Which covalent compound has a melting point of -93C and boiling point of -14C and conducts electricity in water?
Covalent compounds can not conduct electricity whether dissolved or not. There are not any mobile charges available to create a current. However the compound in this question is a gas, not sure which one. But a gas such as ammonia, when dissolving in water can react with the water to form an ion, in this case, Ammonium. The presence of dissolved ions will allow an electric current to flow.
Does water allow the flow of electricity?
Yes, if the current is strong enough. This is why you have to get out of the pool or the ocean when a lightning storm comes ;)
Does water conduct electricity well?
Pure water is a very poor conductor of electricity. Dissolving an ionic compound in water makes the solution a very good conductor.
Does sugar conduct electricity why?
No, sugar does not conduct electricity because it can not ionize, so it does not carry a charge.(in the matter of dissolving it in water!)
What are the five types of electricity?
AC specifies alternating current and DC means direct current.
When ionic substances are dissolved in water do they conduct electricity?
Yes. Dissolving an ionic compound gives you ions in the water which are free to move in an electric field.
Is alkaline water a conductor of electricity?
Yes. If water is alkaline or acidic that means ions are present. Ions are what allow water to conduct electricity.
Ions which allow a solution to conduct electricity are known as?
Salts that ionize in water and form solutions that can conduct a current are called electrolyte.example: sodium chloride,potassium chloride.
What measure of electricity is similar to gallons per hour of water?
Current
Is dissolving in water a chemical change?
Dissolving in water is a physical change.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change.
Why ocean water is not used to produce electricity?
I think it can be with various water turbines and water current transformers.
