Na+ and Cl- are spectator ions.
One important truth is that it is not balanced, because it has five chlorine atoms on the right side and only two chlorine atoms on the left. The equation should read: 2 FeCl2 + SnCl4 -> SnCl2 + 2 FeCl3. The equation also describes an oxidation-reduction reaction, in which iron ions are oxidized and tin ions are reduced.
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
They are identified in the cavity bb U.S. Pat. 4.512.577and 4.621.813

Iron ions with 2+ are known as ferrous and with 3+ is called as ferric.
Ions with a 2 plus charge are called cations. They have lost two electrons, resulting in a positive charge. Examples include calcium ion (Ca²⁺) and iron(II) ion (Fe²⁺).
Cations.
Plus charge, ie, it has H3O^+ ions (hydronium ions)
b. Fe3 plus ions
Aluminum is a metal that commonly forms ions with a charge of plus 3.
In the ionic compound FeS (iron sulfide), the iron ion has a charge of Fe2+, meaning it has lost two electrons. Sulfide ions (S2-) balance the charge by accepting two electrons from each iron ion.
Two ions with a +1 charge will bond with one ion that has a +2 charge to maintain overall electrical neutrality in the compound.
Two ions with a +1 charge will bond with one ion with a -2 charge to form a neutral compound. The ratio is determined by the charges on the ions, ensuring that the overall charge of the compound is balanced.
Fe 3+andOH -form the ionic compoundFe(OH)3-------------------------ferric hydroxide, or the modern name, iron (III) hydroxide.
Ions with a 1+ charge are formed when an atom loses one electron. Elements like sodium (Na), potassium (K), and silver (Ag) commonly form 1+ ions.
