Avicel pH 101 used in wet granultion and Avicel pH 112 is DC excipient.
"PH" designation indicates that the product is suitable for pharmaceutical use.
PH 75 is the most acid.
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
Avicel pH 101 used in wet granultion and Avicel pH 112 is DC excipient.

Microcrystalline cellulose is commercially available in different particle sizes and moisture grades which have different properties and applications.Avicel PH 101Has a nominal mean particle size of 50 microns

There is no difference. Avicel is the brand name of the first microcrystalline cellulose on the market.
Avicel is crystalline cellulose, whereas cellulose is soluble cellulsoe, which is synthesized by the alkali-catalyzed reaction of cellulose. Endocellulase works at CMCase wheras, the exocellulases work dominantly at Avicel.
It act as a stabilizer or suspending agents.
number indicates particle size in microns
pH = pKa - log([HA]/[A])[HA] = concentration weak acid NH4+ and [A] = concentration of weak base NH3 Before HNO3 addition [HA]= 6.0 mmol NH4+ in 100 ml => after: [HA]= 6.0+5.3 mmol NH4+ in 101 mlBefore HNO3 addition [A]= 11.5 mmol NH3 in 100 ml => after: [HA]= 11.5-5.3 mmol NH3 in 101 mlThus: (notice that pH of buffer is independent from a large range of dilution)pHbefore = 9.24- log10(6.0/100 / 11.5/100) = 9.24 - log10(6/11.5) = 9.52and:pHafter = 9.24 - log10(11.3/101 / 6.2/101) = 9.24 - log10(11.3/6.2) = 8.98
