Mar 02, 2019· The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

May 16, 2018· The pH scale ranges from 0 to 14 with 7 indicating neutral pH. The low end of the scale represents high acidity while the high end represents alkalinity. Acid levels in rain or runoff can negatively affect flora, fish and microorganisms. Possible sources include acid rain and mine drainage.
