“…Peterson (1966) has shown that waters in the Pacific are unsaturated with respect to calcite except at the surface. Morton and Lee (1968b) have demon· strated the importance of ion pair formation, particularly with magnesium, on CaC0 3 formation in ocean waters.…”

“…The Earth's crust consists of about 3.4% (by mass) calcium. Calcium exists primarily as calcium carbonate, calcite, chalk, and marble on Earth or in the ocean (1)(2)(3)(4). Acid rain has become a serious environmental problem in most industrial countries as it can destroy buildings, monuments, and statues with high calcium carbonate content.…”

The purpose of this article is to demonstrate the use of a datalogger in conjunction with a pressure sensor to monitor the generation of carbon dioxide when calcium carbonate is in contact with hydrochloric acid. This method is used to determine the calcium carbonate content in eggshells. This experiment provides hands-on experience for students in an advanced placement or second-year high school level chemistry course to gain understanding of a pseudo first-order reaction and determine the major component of eggshells.

“…Another example involving the calcium carbonate equilibria in lakes has been cited by Morton and Lee (31). Although the authors did not treat the possibility of ion pair formation, they do conclude that "more accurate ion pair data is needed before the possible role of ion pair formation in dilute lake waters can be determined".…”
