The acid content of the paper is a good indicator of its service life. It can be measured by the pH value between 0 (acidic, indicating that the life of the paper is very short) and 14.0 (alkaline, indicating that the life of the paper is very long). The acidity of any paper increases with age and exposure to sunlight and air. Acidic values have a pH of less than 7.0. For example, the newspaper you read every day is made of acidic paper, and if you take care to store it, it will probably last about 20 years, but if you expose it to sunlight and air, it will probably only last a few weeks.
Acid-free means that the paper has a pH of 7.0 (neutral) or higher (alkaline). Under normal conditions of use and preservation, acid-free paper can last up to about 200 years.
