What is Negative Water?

Published in Water Chemistry 1 min read

Negative water, in simple terms, is water that has been electrically charged to have a negative charge, measurable in millivolts (mV) using an ORP (Oxidation-Reduction Potential) meter. This negative charge is often associated with an abundance of electrons.

Here's a breakdown:

  • How it's created: Water can be charged negatively by running electricity through it. Experiments have demonstrated that water dripping from a biased metal needle can acquire a net electric charge that can be stored.

  • Measurement: The level of negative charge is quantified using an ORP meter. The meter reads in millivolts (mV), with more negative readings indicating a higher concentration of electrons and thus, more "negative" water.

  • Electrons and Charge: The "negative" characteristic refers to the abundance of negatively charged electrons in the water. This surplus of electrons is what gives the water its negative charge.

It's important to note that the term "negative water" is sometimes used in marketing contexts related to alkaline water or reduced water. While there might be some overlap in the properties attributed to these types of water, the scientific understanding of "negative water" is primarily based on its electrical charge as measured by an ORP meter.
