Could a positive-polarity description be confused with pH or alkalinity?
Positive polarity here is an electric charge.
It is not a pH value and says nothing about acidity or alkalinity. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The coulomb is the unit of electric charge. The National Institute of Standards and Technology gives the quantity the coulomb measures as “electric charge, amount of electricity.”
