Detailed explanation-1: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-2: -(non-acidic, or alkaline foods have pH values of 7.0 or greater) . They include red meats, seafood, poultry, milk, and all fresh vegetables except for most tomatoes.

Detailed explanation-3: -pH is measured on a scale of 0 to 14. On this scale, a pH value of 7 is neutral, which means it is neither acidic nor basic. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more basic.
