If you add Na₂CO₃ to a solution of Ca²⁺ and Mg²⁺, which carbonate precipitates first if both are 0.01 M? ((K_{sp}) CaCO₃ = 4.8×10⁻⁹, MgCO₃ = 6.8×10⁻⁶) A: CaCO₃ (requires [CO₃²⁻] = (4.8 \times 10^{-7} M)) vs MgCO₃ (requires (6.8 \times 10^{-4} M)).
Fractional precipitation is an important technique in chemistry that allows for the separation and purification of compounds. The Pogil activity on fractional precipitation provides students with a guided inquiry approach to understanding the concept of solubility and its application to the separation of ions. By working through the activity, students can develop a deeper understanding of the principles of fractional precipitation and how it is used in real-world applications. Fractional Precipitation Pogil Answer Key
The critical calculation involves the relationship: If you add Na₂CO₃ to a solution of
