Question
5 out of 15
 

In some reactions, you will often encounter ions in aqueous solutions which are not actually involved in the reaction. Such ions are best termed:

A Cations
B Anions
C Salt-bridge ions
D Spectator ions
Ans. D This is a straightforward definition-type question. The ions that are present in the solution sometimes do not actually participate in the reaction. By writing the complete ionic equation of such a reaction, we can see that the spectator ions on both sides of the equation are in the same state or form. We can cancel them out and get the net equation of the reaction. Spectator ions are not usually depicted in the net ionic equation.
