This Brings It All Together....

a: Double displacement ~
b: when partners swap dates

What: Double displacement is like when partners swap dates, for example when KI is mixed with AgNO3, Ag pairs up with the I and K pairs up with the NO3. Positives can only be paired up with negatives. Then you check on the solubility chart. Iodide is not soluble when paired with silver therefore you can conclude that that is the identity of the precipitate.
