A weak acid dissociates in pure water according to the equilibrium
HACAU + H200 H30+20 + A 9
1. The weak acid, HA, has an acid dissociation constant, Ka=7.2999999999999998x107, is added to
water at a concentration of 0.51000000000000001M. (construct an ICE chart to assist)

a. What is the H30+ concentration in solution?
HAW + H201) + H30+4 + Acam

b. Describe how and why the addition of highly concentrated (not affecting solution volume) HCI
will affect the A- concentration. Justify your answer.

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.
