All scrapbook supplies should be acid free and lignin free including album, paper, stickers, pens and adhesives because acid and lignin destroy photographs over time causing them to fade, turn yellow, and/or become brittle.
The paper industry has test procedures and standards related to pH, alkalinity, and lignin content for both coated and uncoated papers to be used for archival purposes. The relevant standard for such applications is ANSI Z39.48, "Permanence of Paper for Publications and Documents in Libraries and Archives."
