Sodium carbonate molecules dissolve in water into charged particles called ions. An ion having a negative charge, such as CO3-2, is called an anion because it moves through its solution to the positive charge on the anode. A particle having a positive charge, such as Na+, is called a cation. It moves through the same solution to the cathode.
