Why can salt solution conduct electricity? Salt solution contains Na+ and Cl- ions. When ions are present in the solution, these ions can move through the solution to carry an electric current.
How does salt conduct electric current? When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely, increasing the conductivity. These ions are what carry electricity through the water with an electric current. In short, saltwater (water + sodium chloride) can help to produce electricity.
Is salt solution conduct electricity or not? Salt solution such as sodium chloride (NaCl) conducts an electric current because it has ions in it that have the freedom to move about in solution. … This movement of ions to opposite ends of the electrodes allow electric current to flow through the solution.
When did we start using electric trains? The first electric passenger train was presented by Werner von Siemens at Berlin in 1879. The locomotive was driven by a 2.2 kW, series-wound motor, and the train, consisting of the locomotive and three cars, reached a speed of 13 km/h.
