The net ionic equation for mixing aqueous AgNO3 with aqueous KCl is
Ag+ (aq) + Cl– (aq) → AgCl(s)
Which statement best explains why NO3– and K+ do NOT appear in the net ionic equation?
a) Their charges neutralize each other, so they cancel out of the equation.
b) They remain dissolved as ions that do not change during the reaction.
c) Their very high solubility makes them effectively part of the solvent, not the reaction.
d) Only species undergoing oxidation or reduction are shown, and their oxidation states stay the same.
