How can solution pH influence a fluorescence measurement?

) Explain how temperature and pH levels can influence microbial infections in the human body.
1) What can you use fluorescence lifetime (FLIM) measurements for and what is the advantage compare with fluorescence intensity measurements? I have difficult to understand why FLIM is a better technique than fluorescence intensity? by better I mean the advantage FLIM have comparing to fluorescence intensity method? They say its better because FLIM is indenpendent of change in fluorescence intensity, and fluorophore concentration. But in FLIM measurement we measure the intensity of flourophore versus time? just like the fluorescence intensity...
How does temperature and salinity affect a pH measurement?
How can one simultaneously increase both the sensitivity and the detection limits in fluorescence?
How does PH influence enzyme activity? How might a change in environmental pH due to acid precipitation or carbon dioxide pollution impact an ecosystem?
help please!!!!

What volume of 0.05M H2SO4 would be needed to be added to 100 ml volumetric flasks to give solutions at your chosen pH? Hint: Estimate the magnitude of the error for a measurement if the pH of the solution was actually 4.5...
In a brief paragraph, describe how a salt can affect the pH of a solution. How do the Anions and Cations of the salt differently affect the pH? How would the following salts affect the pH? Raise pH? Lower pH? No Effect? CsCl (Cesium Chloride) NH4Br (Ammonium Bromide) NaCN (Sodium Cyanide) NH4F (Ammonium Fluoride)
