Fractional Precipitation Pogil Answer Key Updated Link

generally means the salt is less soluble and will precipitate first if ion concentrations are similar. cap Q sub s p end-sub (Reaction Quotient): Used to determine if a precipitate will form ( Common Ion Effect:

The key to understanding fractional precipitation is , a measure of how much of a compound can dissolve in water. A smaller Ksp value means the compound is less soluble and will precipitate first when its ions are present. In the example above, AgI's much smaller Ksp explains why it precipitates before AgCl. fractional precipitation pogil answer key

): This is the equilibrium constant for the dissolving of a slightly soluble ionic compound. Example: For generally means the salt is less soluble and

For salts with the same ion ratio (1:1 like AgCl and Hg₂Cl₂), the smallest Ksp means the lowest solubility. However, careful: Hg₂Cl₂ is actually Hg₂²⁺ + 2Cl⁻ → Hg₂Cl₂. You must calculate the [Cl⁻] needed to start precipitation. In the example above, AgI's much smaller Ksp
