Temperature and impurities
yes
Temperature Dissoved Oxygen pH level
acid can dissolve wood with its high chemiacal ph level
Acidic substances will lower pH and more alkaline or basic substances will put it above the neutral value of pH = 7
unfortunetly YES, it has a ph level aound 4.5 and mouth ph normal level is 7.
The pH of the mouth is very variable; sometimes 5,5-6,0. however, on an average basis, it is 7, or neutral.
The level of acidity
If the pH level is to high or low, it can kill the animals in the river.
Ph levels affect the balance of things. If an ecosystems Ph level is off, it can cause a surplus in bacterial growth.

Ionic strength doesn't affect pH
Temperature and ph level.
Temperature and impurities
Ph level, enzyme concentration, substrate concentration etc
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
