Question:
A solution contains {eq}0.20 \ M \ Cl^- {/eq} and {eq}0.20 \ M \ SO_4^{2-}. {/eq}
a) Identify a cation that could be added to the solution to give a precipitate with only one of these anions.
b) Write the net ionic equation for the precipitation reaction in part a?
Cation
A cation is a positively charged ion. A cation can be polyatomic, which means it has more than one atom, such as Ammonium {eq}(NH_4^+) {/eq}. A cation can also be a single atom such as Magnesium ions {eq}(Mg^{2+}) {/eq} or Sodium ions {eq}(Na^+) {/eq}. Cations can mix with anions to form salts for example {eq}Na^+ + Cl^- \to NaCl {/eq}.
