TABLE:
| Reaction Example |
|---|
| $$Pb(NO_3)_2 (aq) + 2KI (aq) \rightarrow PbI_2 (s) + 2KNO_3 (aq)$$ |
A
$$Pb(NO_3)_2 (aq) + 2KI (aq) \rightarrow PbI_2 (s) + 2KNO_3 (aq)$$
B
$$K_2SO_4 (aq) + NaCl (aq) \rightarrow Na_2SO_4 (aq) + KCl (aq)$$
C
$$NaNO_3 (aq) + KCl (aq) \rightarrow NaCl (aq) + KNO_3 (aq)$$
D
$$NH_4Cl (aq) + NaOH (aq) \rightarrow NaCl (aq) + NH_4OH (aq)$$
