Hydrolysis of hemiacetals

All parts of this problem involve the preparation or hydrolysis of hemiacetals or acetals (or the corresponding ketone derivatives). See Sec. 9.7. 

It is the relative ease of hydrolysis of hemiacetals I and II from a polysaccharide that is so attractive in effecting dispersibility. Glyoxal-treated xanthan gum and other gums are very dispersible because of their relative insolubility but as the acetals are hydrolyzed, the gums begin to hydrate at a rate that allows each gum particle to remain separated to form lump-free solutions. 

Equilibrium conditions govern the formation and hydrolysis of hemiacetals and acetals.
