A solution contains 0.010 M F− and 0.010 M CO32−. If Mg2+ is slowly added to the solution, which ion will precipitate first? What is the maximum concentration of Mg2+ that can be used to selectively precipitate out one metal ion, leaving the other ion in solution? The Ksp of MgF2 is 5.0x10−9 and the Ksp of MgCO3 is 5.0x10−8.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
