Interpretation: To give the steps of deacidification methods.
Concept Introduction: The method of treating paper for the neutralizing acids within the paper is known as deacidification.
Answer to Problem 117A
The process of treating the paper is called as deacidification method.
Explanation of Solution
The method of treating paper for the neutralizing acids within the paper is known as Deacidification. They are either aqueous or non-aqueous solutions. Most deacidification processes are used to neutralize acidity it uses some earth-alkaline metals.
The first step in popular deacidification methods is to immerse the paper in a dilute solution of calcium hydroxide.
The chemical equation representing the deacidification step can be depicted as follows:
Calcium bicarbonate is treated with calcium hydroxide yields calcium carbonate and water. The precipitate calcium carbonate is formed.
Thus, the process of treating the paper is called as deacidification method.
