for the list of chemicals below, write complete, balanced equations for all possible reactions that would lead to an insoluable salt.
KCl, BaCl2, AgNO3, Pb(NO3)2, K2SO4, HNO3
To do this problem you need to know the solubility rules. Here is a simplified set. Memorize them. Use #4 (sulfate) and #3 (chlorides) as examples. I will leave the others for you.
BaCl2(qq) + K2SO4(aq) ==> 2KCl(aq) + BaSO4(s)
2KCl(aq) + Pb(NO3)2(aq) ==> AgCl(s) + 2KNO3(aq)
By the way, note the correct spelling of soluble (no a in it).
