alkalinity) of an aqueous solution. It is roughly the negative of the logarithm to
base 10 of the molar concentration, me...
The same holds true for pH values above 7, each of which is ten times more
alkaline (another way to say basic) than the next lower whole value. For example
Milk usually has a pH around 7.0. A pH below 7.0 indicates acidity, while a pH
