[Ag+][Cl−]=Kspopen bracket cap A g raised to the positive power close bracket open bracket cap C l raised to the negative power close bracket equals cap K sub s p end-sub
: The solution is supersaturated; a precipitate will form until Kspcap K sub s p end-sub 2. Which Ion Precipitates First? fractional precipitation pogil answer key best
A common "critical thinking" question in POGILs asks how much of the first ion remains in the solution when the second ion just begins to precipitate. To find this, take the required for the second ion ( from the example above) and plug it back into the Kspcap K sub s p end-sub expression for the first ion: [Ag+][Cl−]=Kspopen bracket cap A g raised to the
Here is a comprehensive breakdown of the logic, math, and chemistry behind fractional precipitation. To find this, take the required for the
