Explanation for Q.25

(The presence of iron is used to determine the age of a document through ink dating. The iron gall ink, which was commonly used in Europe from the Middle Ages until the 20th century, contains iron salts that oxidize over time and cause the ink to change color from blue-black to brown. This change in color can be used to determine the approximate age of a document.

In addition to the oxidation of the ink, ink dating also involves other chemical and physical techniques such as chromatography, spectrometry, and microscopy to analyze and compare the ink samples.

The technique of ink dating is often used in forensic investigations to determine the age of a questioned document or to determine whether two documents were written with the same ink. It can also provide valuable information in historical research.
