Hello!
Could you help me please with such a question:
How do you measure pH of Gold suspension during pH adjustment?
I tried to use a regular pH meter and pH strips during pH adjustment of Gold colloid (OD 1) and I have very big difference between values: for example, pH 5 (pH strips) vs pH7.5 (by pH meter); pH 8-8.5 (pH strips) vs ph 10.15 (by pH meter).
I would be very thankful for any thought/suggestions on this topic.
Thank you!!
