_________ serves as a model compound for the acid ionization behaviour of many carboxylic acid groups.

_________ reactions of secondary and primary amines are analogous where 1 or 2, respectively, of the R groups are protons.

Potato _________ has about 0.1 to 0.3% equivalent PO4 corresponding to a degree of substitution of 0.002 to 0.005.

A high charge density (above the 30% level) tends to completely unravel the normally coiled molecules in solution. What’s the criteria discussed here?

Anionic _________ usually contains about 5% polyacrylic acid groups formed by co-polymerization of acrylamide and acrylic acid monomers or by hydrolysis of P.A.M. homopolymer under conditions to convert some of the amide groups to carboxylate salts.

_________ are relatively inexpensive polymers that are easily devised to high molecular weights on the order of several million (g/mol).

Polymers with charged groups are called _________

A molecule with only carboxylic acid is amphoteric and a zwitterion.

The term _________is often utilized to mean a material containing cationic and anionic groups; strictly speaking, however, it means a material that is both acidic and basic.

Paper making polymers can be categorized as naturally occurring polymers, modified naturally occurring polymers, and synthetic polymers.
