There factors include:
-Ionic strength
The number of ions and charges present affect the ion activity coefficient and hence the activity of charges species in the solution
-Dilution of buffer with water
The pH will change and this will affect the ion activity coefficient. The activity of charges species in the solution is hence affected since water itself can act as an acid or base.
-Temperature
The effect of temperature on weak acids and its conjugate base as a buffer is small due to small changes in its ionization constant Ka as a function of the temperature. As for a weak base and its conjugate acid, the pH is constant only if the temperature is constant. If the temperature fluctuates, the pH changes according to the changes in pKw for water and pKw is very susceptible to temperature changes.

Why doesn't the pH change when a solution is diluted?
Thats a silly question, it cant change if you dilute it, if you dilute it it should stay to an easy pH of 7 or it could change to a weak acid/base. Its not that hard.
Why should you avoid skin contact with the unknown solution?
Because you don't what's in it. The solution could contain chemicals that could irritate or harm your skin.

What could you add the solution to increase the pH?
Using common household chemicals as an example, to change a solution to become more acid, you could add vinegar, to change a solution to move to more of an alkaline you could add baking soda.

Which indicator could be used to identify a neutral solution?
there is no such indicator.the only way is to add the acidic and basic indicators ,if it does not change the colour of the solution then it is neutral.
