An ammonia/ammonium buffer solution contains 0.44 \({\rm \it M}\) \(\rm NH_3\) and 0.88 \({\rm \it M}\) \(\rm {NH_4}^+\). The \(\texttip{K_{\rm b}}{K_b}\) value of ammonia is \(1.8\times 10^{-5}\). Calculate the \(\rm pH\) of this buffer.

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.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
