The distribution coefficient, k = conc. in water
conc. in ligroin
, between ligroin and water for solute A is 7.5. What mass of A would be
removed from a solution of 10.0 g of A in 100 mL of water by a single extraction with 100 mL of ligroin? What mass of A
would be removed by four successive extractions with 25-mL portions of ligroin? How much ligroin would be required to
remove 98.5 % of A in a single extraction?

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.
