I'm running low on pH indicator.
Till I get a new one I thought about using a smaller water smaple with fewer drops.
The standard volume is 44cc with 5 drops.
Running at 40% will be 17.6cc with 2 drops.
I assume that my measuring error will be bigger, just don't know how much.
I can measure the volume of the water sample correctly within 0.1cc.
Comparing the colors is also not an issue since I can turn the comperator container upside down if needed.
Can anyone comment about the excepted pH measuring error?
Thanks,
Avi.
