hey,what about those type of equations that have only one aqueous compound? like H2SO4 + CaCO3 = CaSO4 + H2O + CO2, whereby only sulfuric acid is in aqueous state here, calcium carbonate and calcium sulfate both is solid

Spectator Ion is in AQUEOUS STATE. Check out the example above and see how we determine the Spectator Ion(s).

Hope this helps. Think about it.

Titration only for SPA salts preparation.

SPA = Sodium, Potassium and Ammonium Salts.

Hi,
I just wanted to know if an element changes its state symbol during the reaction then is it still a spectator ion? My head says no because that means that it has taken part during the reaction but I am not 100% sure, and I’d just like to check.
Thanks!
