Question

The most common approach to control paper acidity is to include calcium carbonate (chalk) in the paper mix. As the paper is produced, some of the calcium carbonate reacts with the acid released by the lignin. Write the net ionic reaction for the reaction of carbonate with the acid released from lignin. Use the basic format above where is the stoichiometry (include a number, even if it is 1), "carbonate" "reactant", and "product" are the appropriate chemicals or reagents, including any formal charges, and "state" is the state of matter. Use "A" for a superscript, if necessary.

Explanation / Answer

1 CaCO3 (aq) + 2 RCOOH (aq) 1 (RCOO)2Ca   +1 CO2  + 1 H2O

Lignin contains organic acids like ferulic acid.
