What Happens If You Put Battery In Salt Water. Salt water is much more conducive than regular water so the battery would discharge more quickly. You get hydrogen and chlorine gas and the battery becomes flat.
Once you put battery in salt water the sodium ion migrate towards the negative tank and chloride ion migrate towards the positive tank. A demo I do early in the semester is to drop a fresh 9V battery into a beaker of distilled water and then into a beaker of water with sodium bicarbonate dissolved in it. Salt dissolves in water to leave behind positively-charged sodium ions and negatively-charged chlorine ions.
In short saltwater water sodium chloride can help to produce electricity.
Regardless DC current is needed and you got that right. In saltwater batteries a liquid solution of salt water is used to capture store and eventually discharge energy. Regardless DC current is needed and you got that right. When you put salt in water the water molecules pull the sodium and chlorine ions apart so they are floating freely increasing the conductivity.
