What are the spectator ions?

Answer 1

Spectator ions, in a chemical reaction, are ions that don't take part in the overall reaction. For instance, consider the following reaction:

Pb2+ (aq) + 2 NO3 (aq) + 2 K+(aq) + 2 I-(aq) ---> PbI2(s) + 2 K+(aq) + 2 NO3-(aq)

The bolded and italicized compounds are spectator ions. They do not play an active role in the reaction. So, when these spectator ions are removed, we end up with a net ionic equation:

Pb2+(aq) + 2 I-(aq) ---> PbI2(s)

Answer 2

Spectator ions, in a chemical reaction, are ions that don't take part in the overall reaction. For instance, consider the following reaction:

Lead(II)nitrate and Potassium iodide solutions precipitating (indexed as '(s)' )lead(II)iodide, leaving nitrate anions and potassium cations IN solution (indexed as '(aq)').

Pb2+(aq) + 2 NO3-(aq) + 2 K+(aq) + 2 I-(aq) --> PbI2(s) + 2 NO3-(aq) + 2 K+(aq)

Another name for this is: they are 'tribunated' or 'tribuned' , meaning that they're there just to be present, but not taking part in the 'match' (reaction).

In the net reaction they most commonly are left out:

Pb2+(aq) + 2 I-(aq) -->PbI2(s)

Answer 3

Spectator ions are ions that do not participate in a chemical reaction. They only exist as reactants and products in a chemical equation.

Answer 4

spectator ions are the ions that do not take part in the chemical reaction. They are usually ions that form soluble compounds. Spectator ions often have a single charge and a large radius.

Answer 5

Spectator ions are ions that do not part in a chemical reaction.

Answer 6

Ions that are not changed in the reaction. Apex
