Which two solutions, when mixed together, will undergo a double replacement reaction and form a white, solid substance?
1. NaCl(aq) and LiNO3(aq)
2. KCl(aq) and AgNO3(aq) answer
3. KCl(aq) and LiCL(aq)
4. NaNO3(aq) and AgNO3(aq)
2 is the answer because AgCl is formed and that is a white ppt.
examine all the possible products
of those only AgCl is insoluble
so the answer is (D)
NaNO3(aq) + AgNO3(aq) → NaNO3(aq) + AgCl(s)
