The lower alcohols resemble water, in that they can form the ions ROH. and RO. , but their dissociation is less than for water ((p.=16.7, P.=19.1, cf. p.= 14.0). Consequently, substances dissolved in alcohols are weaker acids and bases than in water. Other factors infl作者: GROWL 時間: 2025-3-24 09:13

The Theory of Buffer Action,An acid is a species such as the ammonium ion or the acetic acid molecule which has a tendency to lose a proton. A base (such as the ammonia molecule or the acetate anion) is able to accept a proton. Hence for every acid, HA, there is a conjugate base, A., and for every base, B, there is a conjugate acid, BH..作者: Bouquet 時間: 2025-3-25 13:22
Appendices,Tables 10.1 and 10.2 enable buffer tables to be constructed for use at a constant ionic strength of 0.1 for monoacidic bases or monobasic acids, given the appropriate ‘practical’ p.’. Where necessary, this can be calculated from the thermodynamic value in Appendix III by using Table 2.3.作者: Seizure 時間: 2025-3-25 17:26

Practical Limitations in the use of Buffers,se. For a buffer to be effective, its pH must be within the range p. ± 1, or preferably, within p. ± 0.5. The former scarcity of buffer substances with a pH range 6 to 8 frequently led to the use of buffers such as phosphate or Tris in pH regions where they had little buffer capacity.作者: hegemony 時間: 2025-3-26 01:05 作者: 敵手 時間: 2025-3-26 05:41

In recent years there has been a significant expansion in the range of available buffers, particularly for biological studies, largely in conse- quence of the development of many zwiUerionic buffers by Good et al.
