Surface water typically has a pH value of 6.5 to 8.5 (7 represents neutral on a scale measured from 0 to 14). Acid water is classified as water with a pH value lower than 7. Household liquids considered naturally ,acidic, are coffee and vinegar. Household items with a pH above 7 – common examples include baking soda and soap – are ,alkaline,.
