4、Each species has the ability to grow within a specific pH range, which may be broad or limited, with the most rapid growth occurring within a narrow optimum range.
2、The optimum pH range for combined degradation was in weak acidic.
1、However, if optically active reagents are being used it would be important to avoid the pH range above 6, as at the higher pH range interconversion of the free compound of Formula I occurs.
3、Determination of suitable pH range of the dye both for the dyeing of acrylic fibres with cationic dyes
6、The pH response to temperature varied in different pH ranges of the aqueous solutions, and colors changed when acid-base indicators were added to the aqueous solution.
5、The variation of this pH range was dependent on the strength of the base, the volume of the conjugated acid cation, and whether this cation can increase the surface charge of the micelles or not, etc.
