You’ve probably heard of the chemical calcium in milk. But calcium shows up in lots of other stuff too ... One of the most common chemicals connected to calcium is called “carbonate”, and together ...

In this reaction we will investigate the reaction between ethanoic acid and calcium carbonate. All acids produce carbon dioxide gas when reacted with a metal carbonate.

A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium ...

"This is one of the first demonstrations of microbial dissolution of calcium carbonate at a higher pH," said Karrie Weber, professor of biological sciences and Earth and atmospheric sciences.
