The pH range for carbonate-bicarbonate buffer is 9,2.
the pH range is around 10
The chlorophyll is usually acidic. The PH range for safe chlorophyll stability should be between a PH of seven and nine.
It is important to know the PH of various substance so as to prevent damage to the human beings and certain materials. The knowledge of PH is also important in environmental and water analysis.
optimum pH is 7.3
Water
4 and 6
pH is based on the ionic product of the water. At ionic product of water reaches to 100, then the pH of the solution is 14.
"Dirty" does not define any particular pH range for water. Water can be contaminated by acids, alkalis or neutral materials.
The specific gravity [relative to water] is 0.91
Most natural lake waters range from PH=6 to 9
6.5 to 8.5 is right answer
Can be anything, there's no strong link between pH and temperature. -------------- When the temperature is increasing the pH of water is decreasing and the ionic product (Kw) is increasing; at 50 0C the pH of pure water is 6,43. See the link below for the theory and for a table of pH.
The pH is dependent on the gas nature, concentration, pressure and temperature.
The range of pH values is 0 - 14.
The pH of tap water varies a great deal from town to town and sometimes from one season to another. Your city water department can give you a general idea of your tap water's pH, but it would be better to buy a wide-range pH test kit and test it yourself.
7-14 is the range of base in a pH scale
