Best Answer

Positive hydrogen ions will move to the negative terminal of the battery, and negative oxygen ions will move to the positive terminal. If the terminals are iron, the oxygen and iron atoms will react to create Iron(III) Oxide (Ferral Oxide), or rust. The stronger the battery, the faster the positive terminal will rust. If the terminals are anything other than iron, the hydrogen and oxygen atoms will simply separate, causing the water to bubble.

Adding enough salt to water, even at room temperature or lower will result in sufficient salt being dissolved in the water to make it have a salty taste, making it salt water. technically you need the application of heat and or pressure otherwise you just have some salt sitting in some water
