Back titration determination of the carbonate content in …
amount of calcium carbonate cannot be determined by simply titrating the garden lime with the acid. Instead the technique of back titration as aforesaid must be employed. The lime is first reacted with an excess of acid and heated to release all carbon dioxide.
Oxide - Oxides of phosphorus | Britannica
Many metal carbonates liberate CO 2 when they are heated. For example, calcium carbonate (CaCO 3 ) produces carbon dioxide and calcium oxide (CaO). CaCO 3 + heat → CO 2 + CaO The fermentation of glucose (a sugar) during the preparation of ethanol , the alcohol found in beverages such as beer and wine , produces large quantities of CO 2 as a by-product.
