How pH effects Stability and Activity of Enzymes?
Enzymes are very pH-sensitive. Any change in pH results in denaturing of proteins.
What is the pH range for carbonate bicarbonate buffer?
The pH range for carbonate-bicarbonate buffer is 9,2.
PH mitric method for determination of stability constant?
Yes it can be determined by monitoring the change of the pH with time. Suppose you have a compound that is almost constant upto certain time but after some time the pH is getting decreased .So this is the point where your compound is degrading so at that pH calculate pKa and from there the stability constant.
What is the pH in laundry detergents?
the pH range is around 10
Why are these pigments unstable in the presence of light or heat energy?
Chlorophyll: Reaction with heat depends on pH. In a basic solution (pH 9), chlorophyll is stable, and in an acidic solution (pH 3) it is unstable. When heated, the cell membrane of the plant deteriorates, releasing acids, which decrease the pH. This results in the magnesium atom being displaced by two hydrogen ions, resulting in the formation of olivebrown pheophytin complex. This cell degradation during heating also makes the chlorophyll more susceptible to photo-degradation. *When chlorophyll undergoes heat process, it will turn dull olive brown.
What is the pH of Chlorophyll?
Because chlorophyll is a pigment, it can have a variety of pH levels. Chlorophyll generally takes on the pH of the substance it is immersed in, which likely includes soil and water. In whole, chlorophyll, like many other substances, does not have a specific pH value.
How you can do stability of Ranitidine infusion?
Jst keep the solution in the pH range 6 to 7 with a phosphate buffer..... Thanks, Bidya Sekhar
What is the range of pH?
The range of pH values is 0 - 14.
What is the normal range for safe drinking water?
700000 degrees farinheight
How pH effects Stability and Activity of Enzymes?

What is a pH range of a base?
7-14 is the range of base in a pH scale
What the safe pH of the soap?
pH 5.5 which is about the same pH as the skin.
What factors affect enzyme stability?
temperature (most of them denature above 45* C ), pH (best range is 4.5 - 8.1), inhibitors (ions used for fractionation, chelating agents)
What is the pH range for carbonate bicarbonate buffer?
The pH range for carbonate-bicarbonate buffer is 9,2.
Acidic foods with a pH over 7.5 are an ideal breeding ground for bacteria?
PH values greater than 7 are alkaline, not acidic. Anything outside the PH range of 4.6-7.5 are generally considered safe. A food with a PH of 7.5 is safe to leave at room temperature, but you would want to be fairly certain it's not any lower. Especially if you plan to serve it.

What is the pH value of tamarind juice?
It must be different from pomegranate to pomegranate but at least it is reported in a scientific article that it is 3.2.Here is the article, it is about the thermal stability of pomegranate juice:http://www.springerlink.com/content/hp57l57027637l18/
