Variables for pH testing and Temp (1 Viewer)

[Anthrax]

i need some variables for taking water temperatures

this is what i have so far
- The length of time that the thermometer sits in the water
- The area that the thermometer sits in the water.

and some for pH, but i cant think of anything

any help would be great

Are you after 'things to measure' or 'sources of error'. When you say pH, do you mean measuring pH or the pH itself. If the former, which method or all?

Temperature measurements can and should be corrected for atmospheric temperature, since most of the glass is in contact with the atmospheric temperature.

pH is effected by the ionic strength of the solution.

for pH measurements see;

Let me know roughly what you want...
