The “alkaline” in alkaline water refers to its pH level. The pH level is a number that measures how acidic or alkaline a substance is on a scale of 0 to 14. For example, something with a pH of 1 would be very acidic and something with a pH of 10 would be very alkaline.

Normally neutral water PH is 7 and alkaline water is within the range of PH 8-9. Inorder to raise the PH of the water, it is treated via an ionizer by electrolysis.
