pH Meter

IOOml HCl (30%) 200ml Water
Figure2: Illustration of the second experimental setup which allows the
measurement of pH value in the presence or absence of concentrated HCl
about 500cm away from and behind the water being measured. If no quantum
entanglement is involved, the presence or absence of the HCl should not affect
the pH value.
