It varies from about -50 mV to + 50 mV. Retention’s often at a max. when the charge density is near 0. This is probably where the solubility is the least. What property’s mentioned here?

The _________ is a colloidal effect having to do with charge distributions upon the surface of the visible suspended particles.

Al ions in solution form polymers by sharing _________ groups.

Alum’s not used in rosin and A.S.A. sizing, as a retention aid, and as a drainage aid.

Al ions in solution form polymers by sharing _________ groups?

This role of _________ in coordination chemistry in retention has been very clear for decades to textile chemists that describe the caustic action of alum in textile dyeing-the same thing that occurs with rosin sizing.

_________ is the central chemical in wet end chemistry and has gained much attention. There are various papers describing the behaviour of alum during papermaking process that generally contradict with each other.

A variety of _________ aids were tested, and anionic polyacrylamides (P.A.M.) of high molecular weight had the most pronounced effect, with 0.5 percent causing up to 65 percent decrement in flocculation.

_________ had an important effect although the value depends on the pulp consistency; under one set of typical commercial conditions, flocculation would change by 1.2 times.

Mechanical properties of fibers were much more crucial than chemical aspects of the slurry.

Formation is clearly dependent on fiber _ which makes it very crucial. They used a pilot plant machine to evaluate numerous factors on fiber _
