pH value of the water: The ideal pH value for our drinking water

What is pH?

The pH value (Latin potentia hydrogenii) is a measure of the concentration of hydrogen ions in a solution . If there are many hydrogen ions in a solution, it is acidic. If, on the other hand, there are few, it is called a basic solution.

The pH value is usually given on a scale of 0 to 14 , with 7 being the neutral mean. Anything below this average is called “sour”. Anything above that is considered “basic” or “alkaline”. The further the value is from 7, the stronger the acid or base. 

pH value: acidic or basic?

To put it simply, the pH value indicates whether an aqueous solution is acidic or basic . But what does that mean exactly?

We encounter acids and bases every day - be it in coffee at breakfast, in tomato salad at lunch or in soap when washing our hands. Coffee, tomatoes and vinegar are acids, while soap is a base. The names of the liquids often tell us something about their classification on the pH value scale. For example, stomach acid is a classic representative of acids and caustic soda is an important base.
